NP435 Conversion.

Well, long time coming but I have started on the Transmission swap on my 79 CJ7 . Health issues and life in general has kept me from getting it going but necessity has dictated and required I get it started. Pulled the rear drive shaft, unhooked the speedo cable, went topside to remove the stick shifter and boots. Also got my retractable seat belts installed as well. Ran out if time.

Next steps will be to remove the trans bolts, go under to get the bottom bolts then use my ATV to secure the whole assembly, drop the six skid plate bolts and take the front drive shaft lose and then slide it out and down.

I have taken this trans out a couple times. But I have an NP435 to go in it's place. It has a Dana 300 tranfer case bolted to that. Should be a good setup.

To anyone here who has done this swap. How do you like it and what were some of the issues if any you ran into?

Anyone use the stock skid plate on this swap?

How about reverse light hook ups? What did you do for that?

Just an update. It's finally in. I had some Tom Woods driveshafts built and came out great. I can say it was a very tight fit, which I guess is good. I have to shim my pinion up but no biggy. I have drove it a ways also and runs through the hears good. The NP435 gear ratios match up well with my 3.45 ratios. I have my twin stick Dana 300 now as well. I figured out how to use my stock skid plate as well without carving it up. But I will exchange it for an aftermarket at some point. Things left are exhaust y-pipe clearance issues, boot for the shifter, and that's about it. Glad to get it done. I'm glad I did the conversion.

So how did it go with the reverse lights ?
