yj tub on a cj frame

I've run into a little problem lately and know that this is the place for help.

My 84 cj body had a couple of rust holes in the rocker panels - no problem, i'll just grind off the paint around the holes, cut out the rust and weld in patches. I started grinding and the more I ground, the more bondo I found - over 1/4" thick in some places. Under the bondo, the metal was almost rusted away. Out comes the sawzall. Now, I have no rocker panels, rear fenders, wheel wells, rear corners, rear body mount crossmember or bed floor.

I have found a 90 or 91 (can't remember) yj body that I can get for $1000. The yj has no motor/transmission - it had a v-8 and auto and was about to be lowered and made into a street rod. I have not looked at it, but was told that the "4-wheel-drive stuff had been taken out". I do not know yet how much has been removed or changed.

My questions are: Will the yj tub line up with the cj fenders and cowl? How about using the cj dash in the yj tub, will it work? Any other problems I may run into? How much labor would this take?

I have thought about using 1" square tubing to frame up the sides, corners, etc and using 18 ga sheet to skin the framing. Not wanting to build a tube buggy, I was gonna frame the door openings, etc to match the factory dimensions as closely as possible. What are the thoughts on this?

I have use of typical machine/fab shop tools, ie shear, press brake, lathe, vertical milling machine, welders, etc, so I can build just about anything I need. I just want to keep the time/labor to a minimum.

I know that I could put my drive train into the yj, but I want to keep the cj as close to original as possible, because I like the big round headlights and the lack of a computer. I also like the cj gauges. I also want to keep the body steel because of my access to the metal working equipment. I can repair a steel body easier than a fiberglass one.

thanks in advance for any help,

The hood and fenders will bolt to the YJ body, so will the dash.

I ran into the same thing on mine, but in my case it was the rocker trim and decals that were holding the rusted metal together. I never noticed. I bought the Jeep with tearing it apart and rebuilding it in mind, so I really just bought it because it had a good frame and body. Once I got to stripping the body bare it became apparent that I was in for more work than I thought. I've thought about doing the YJ tub conversion, but I have already made new front floorboards and welded up the holes along the rockers and I really want to get this thing back on the road this summer. All I've really got left is to patch the ripped out tire carrier holes and patch the rear wheelwells, so I guess I'll go ahead and finish this one. If I keep it maybe I'll do it next winter.
