I mention the wheel wells of the CJ7 because I already have the metal. My intent was not to use the entire piece. Here is the type of fender I want to use: Single Axle Trailer Fender - Jeep Style - 16 Gauge Steel - 13" to 15" Wheels - Qty 1 Redline Trailer Fenders J101936 
I was thinking I would use part of the CJ7 wheel well on the inside of the bed and buy the fenders I linked. I would connect the two to make the opening for the wheels. 
To not cut into the side of the bed for wheel clearance I would have to narrow the bed so much, it would be useless. 
So, I will do both, cut into the bed as little as possible and add a fender to the outside. Hope that makes sense. 
I may just end up using the bought fenders, let them intrude into the bed, and add some flat sheet metal to cover the inside hole. I still have all of this to figure out, but would like to set it on the frame first to see how much room I will need. 
from the metal. I have a little air scraper tool I got from HF. It worked really good getting the tar off. Along with some paint thinner, I got down to bare metal. Good lesson here, if they had just kept it painted or even with tar, there wouldn't be any rust! 
Inside it wasn't much better. Need that air conditioned garage! 
As you can see in this picture there is a large area of rust on the front bed panel. 
First thought was to gut this out and just add a piece of sheet metal. After getting into it I discovered that the sheet metal make the round bend at the top and then joins together at the point of rust to form a sandwich that goes all the way to the bottom. 
If I dress it up and take care of the rust on the inside, I won't have to worry about replacing the whole thing. Here is the bottom half that I cut out.
The plan is to replace it with a single heavier sheet of metal. I was kind of lucky that somebody had welded a piece of flat metal near the top between the sides. This really helps maintain the position of the side while I repair the front panel. As you can see in the next picture.
It will be much more functional for my purpose. I can say that I really use my trucks, and this one will be no different.
I stood for 2 hours in front of my 1st Sargent's office to ask for permission to leave the base to get married. I doubt you can count on one hand the number of people that can say they got married during basic in recent history. So the surprise of renewing our vows was a really big hit. My wife was totally surprised. She had no idea. She didn't realize what was going on until she started to walk out to the ceremony area. I had a really good friend of ours that is a Pastor from Illinois preform the ceremony. There wasn't a dry eye in the crowd. Even the caterer had tears. It was awesome. Here are a couple of pictures I will share with ya'll. This is at the Ring Mountain Event Center. It is located just north of us. We live in the beautiful Hill Country of Texas as you can see in the pictures.
Hard for her to say no about anything now. Says Rod "Yeah Dear I'm going to convert the Jeep into a pick up while I'm at it." Her reply "Sure anything you say Dear."
I built a wood dolly to be able to wheel it out onto the driveway so that I could use my torch to cut off some stuff. :drool: Here are the latest pictures:
Put it in some Phosphoric Acid to clean it up. Will most likely polish it a little. This is definitely a keeper for this truck. 
They were just in too ruff of shape to use. Plans are to cut some new pipe to replace them. 
When I traced the fender for cutting, I was off on the corners. I'll probably have to cut a couple of small pieces of sheet metal to fill in the gaps. Hopefully I'll be able to do a better job on the other side. So the fender is inset 6 inches into the bed and 4 inches stick out of the side of the bed. That 4 inches make it line up with the original width of the Jeep CJ body. I will probably have to cut some of the fenders off at the outer bottom ends. But I won't be able to tell how much till I get the bed actually mounted to the frame. 
Me to. If you want the Jeep logo from my rusted one you're welcome to it.
but I did get good penetration on all of them. 
Then I'll start on the other side and try to reproduce what I just did. I'll also need to cut a couple of pieces of flat sheet metal to weld to the inside of the fender or the outside that faces into the bed. That shouldn't be too hard. 
I will most likely end up adding some sheet metal on the outside of the bed between the bottom of the stake pockets and the fenders, but I don't want do that till it is sitting on the frame. :drool: That way I'll get a better idea of how much I want to add. I also still need to address the front of the bed. I may just buy a replacement piece, not totally sure on that part yet.
