Custom CJ tailgate with YJ top

blog389.webp

Topic today? Another variation of a CJ tailgate with a YJ hard top. A recent trip to the Spring Carlisle auto flee market netted a latch from a vendor that we figured might work for the CJ tailgate that we planned on using with the YJ hard top. There have been several right ups on this conversion, all pretty ingenious in their own way, but for our street only version of this build, they just didn't meet our needs. Those being, lockable, open from the outside without it looking like a utility box and without opening the lift gate, water tight (as much as a stock CJ could be) no protruding latches and be able to sit on it. The fact that a CJ gate opens from the inside versus a YJ from the outside was the problem. A YJ lift gate opens only after the bottom gate is opened, so if you can't get to the inside to open the bottom gate, well I'm sure you get the picture. This is a problem we knew we would face, but was put on the back burner until hopefully a solution fell in our laps. So $5.00 for the latch, we took a chance. I spent more for a Big Smokey sausage sandwich an hour earlier. Once home we analyzed the latch, Jeffrey commented that it looked familiar. Turns out it is the same latch that Poison Spyder TrailGate | Drop-Down Replacement TailGate | Jeep LJ TJ YJ Exterior Upgrades | Poison Spyder Customs uses on their tailgates. The latch is made by Southco 62-42-351-3 - Southco and if you can't find what you need from this company you better give up. The latch we used for mock up is not lockable, but a lockable version will be purchased from Southco. Poison Spyder makes a nice quality gate, but we didn't like the exposed latches on the inside. We like a tailgate to sit on, and we were thinking more along the line of hidden, as in two rods hidden inside the gate exiting out both sides into the body.

Did some preliminary measuring and found the latch was thicker than the gate was thick. So a decorative aluminum housing was milled to rectify this. This put the latch out further, and by cutting off some of the extra long shaft it would clear. Started by downloading specs from Southco and cut a hole in the face of a trashed tailgate we kept just for this purpose. Then an access hole was cut on the inside to facilitate hooking up the rods. Later a sheet metal cover will be fabricated to cover the inside hole and will eventually be covered by carpet. An actuating bar was made with a double D hole to slide over the latch shaft and bent to clear the clamp screw that holds the latch in place. Two holes are drilled and tapped 6-32 to fasten the rods. Two bushings were cut from 3/16 brake line tubing for the 6-32 screws to pass through and tighten down without pinching and binding the flattened ends of the rods. The rods are 5/16 diameter with one end flattened and drilled 3/16 for the bushings. Holes were then drilled at each end of the gate for the rods to pass through. A slight curve was bent on the flattened end of the each rod to produce a longer movement for body engagement. This also limits the rods from dropping out the inside of the holes. After the gate is mounted to the body for it's final alignment, a dab of grease will be applied to each rod end, then actuated out against the body for accurate hole alignment to be drilled. Factory weatherstripping can be utilized for a rattle free tight seal. So there you have it, another version of a CJ gate on a YJ and you can sit on it and crack open your favorite brew.

Can i do this for my CJ or is this a square head thing? I didnt realize CJ parts fit non-jeeps?:D huh? :cool:
 
So if you are doing this I think you should go further and use a tj top, I have been researching it and I believe it will work with modification to the windshield.

I'll be watching this. If your finished product looks as clean as you sound like you are going for I may have to request that you fab up some extra parts for me.
 
Yea I am going for a very clean jeep here so we will see how it turns out. I will have to ask my dad if he wants to make some more if people are interested.
 
Is the last picture the finished product? Got a better pic?
 
We mocked it up on an junk tailgate we had. Going to have to transfer it over as well as order a similar ltach that has a lock.

Are you going to reinforce the sheet metalon the tailgate where the rods exit the side is the metal there thick enough to not oval out or tear over time. Same question on the tub where you plan to have the rods anchor.
 
Yeh we plan on using a metal or nylon grommet on the gate, most likely nylon to prevent the rods from rusting with usage, as far as the body, that will be determined after the good gate is made and the holes drilled into the body. We don't know yet at this point how thick the fiberglass is in that area, but if too thin then probably a bronze bushing similar to a door hinge bushing will be glassed in. There wont be any stress per say on this area since it is only holding the gate shut. The purpose for this post at this time was focused on the mechanics of the latching system rather than a completed project. Other details will have to be worked out with cables or gas struts or whatever we come up with. We will definitely not let you hanging with an incomplete project. Nothing for this whole build has ever been rushed since we don't have a definite deadline. We always sit back and analyze LOL maybe too much.
 
I like it, this makes me want to convert to a tj top now.

Is that aluminum sieve the only part that you had to fab yourself? Is everything else parts you can purchase off the shelf?
 
JArcher410 what's up with the right tail light? Rod

P51100361_zpsee189ce5.webp
 
pb my guess hes going with a flush look with the tail light i'm thinking on doing it to mine also. when tire swings out it slaps the tail light.
 
Just playing around with different ideas on the lights. Might go with an aluminum flush mount housing. I guess some you keen eyed folks noticed the hinges are upside down. Realized it when I opened the gate and it wasn't flush with the floor. Glad I realized it before I mocked up the holding cables. Doesn't make sense though how the hinges are offset and not flat preventing the gate being flush with the body. They position them in past the body. Am I missing something here? The aluminum piece around the latch was fabricated along with the rods and the part the rods attach to. I just took 5/16 cold rolled heated the end up and flattened it with a hammer (black smith style) and the other part also heated and bent, nothing that couldn't be done with a torch and a vise.

Uhhhh, no, I would say that using a YJ hardtop on a CJ would be the problem.

Instead of hacking up a CJ tailgate and going through all of that to rig a latch, use that time and energy to install the proper top for the application.

Look, I apologize for sounding like a jerk but I've been driving, working on, and building CJs for over 20 years. If you got the YJ top for free or real cheap, that's great, but sell it or trade it for a CJ top OR install a YJ tailgate and sit in the tub when opened. I've seen quite a few YJs with CJ tops and CJs with YJ tops and I always ask "how's that working out for you?" Almost always they say the same thing " bought it cus the ad said it would fit my jeep, I hate the back..."

If you've every had a CJ top on a CJ, you'd understand the dynamics of the design and why it works so well as a matched pair ( the top and tailgate).
The same for the YJ and its tailgate. Mis-matching them makes you think you know more than the engineers that designed this stuff.

Speaking of design and engineering, when you lower your tailgate to sit on it and see that it's not sitting level ( high toward the tub, and low under your knees, try turing your hinges around as the offset hinge compensates for the gate thickness and makes the floor and gate on the same level when lowered ( like a pick up tailgate does)
 
I wouldn't call it a Hack, but instead re-engineering and isn't the what Jeeps are all about. I always disliked having to reach inside to unlock my tailgate even with the softtop on, having to set the levers at the right angle so they don't get caught on the crossbar for the top or the tub opening. I had though of using 2 latches to replace the little levers but it would still require the alignment of the levers. Great idea with the pins and cam.

To OP how is it working out? Are you planning on using the rubber seal on the tailgate and have you made the plates to strengthen the tailgate and tub?

Wow ummm ok dude. It was not a "problem" it was a modification. I don't like the style of the cj top vs the yj. The yj top I have has a rear wiper and defroster, bigger glass area in excellent condition. They are constructed better. Idk why the criticism or butt hurt feelings. This whole jeep is 100% different and done my way.

You're reasoning is flawed in saying it was designed that way and that's what's best. OK then why is 99.9% of cjs running different engines and suspensions. Guess you are the .1% After all just look at the descriptions of the MODIFIED jeeps that you have. I'm sure you modified them to make them better for you.

Yep, I build complete stock CJs accurate down the the last bolt or fully custom Jeeps for rock climbing. I won't destroy a clean stock CJ to make a trail Jeep that's going to see hard use. That's just MY opinion as you have yours. That's cool, no need to get defensive or have your feelings hurt. I like the idea and your creativity. I just think its a lot of "mods" for a defrost and wiper when the top that really works is out there. I wouldn't say the YJ top is better by any means, BUT IF I had a YJ (with a swing out tailgate) it only makes sense to go with the YJ top.
You really think that 99.9 percent of all the CJs still out there aren't running the engine they came with? And because I prefer to use Jeep parts on a Jeep and use the best parts for the job that I'm only 1 percent ??? Don't look up what clean, original stock CJs are going for lately...you'll be surprised.
 
I do think we are shooting off on a tangent here so this will be my last say about it. I applaud individuality of a modified anything and also the determination of an accurate restoration. Some things need to be preserved. But what I started out with was a totally wasted body, a 400 turbo and quadra trac. (How many people use Quadra trac, treated right they are reliable) The only thing usable was the frame and grille. A full restoration would cost me more in the long run since I bartered, traded or fabricated everything so far. My goal was to build a safe reliable fast and enjoyable ride. Hence the wider YJ springs, front and rear swaybars , Dana 44 "s and 4 wheel discs. Outwardly it will look basically stock because I like and respect the CJ look. Individuality is a good thing. A problem arises and it gets re-engineered better. Just look at the rock crawlers. Those guys are ingenious when it comes to building better. Something breaks so it gets remade. Tons of aftermarket support and businesses have been created to support that. To some it is their livelihood. There are a few companies building CJ tailgate conversions out there and why? because the demand is there. The only person I plan on pleasing is myself because it is mine. If I can pass on some ideas that might help another Jeeper then great. Is a pat on the back nice now and then, sure, it's an ego thing. We all have egos. Sure we want others to like what we did, but it's not gonna always happen, and that's OK. The forums are flooded with questions for help and if it wasn't for supportive individuals in this community to pass on experience and knowledge we would all be struggling. How about some pics of that CJ (only in a jeep cj) I'm sure I and others would enjoy them. In the meantime I'll be sitting on my tailgate.

Your tailgate latches are still upside down.:chug:
