Re: need new body-Fiberglass or Steel?
I decided to get a 'glass tub (AJ's) when I started finding alot of rust in the body of my '81CJ7. I thought the old body was too far gone to fix. The AJ's deluxe body is very impressive; very thick fiberglass in all of the right places and thick metal at all mounting locations. It was expensive ($2,000+), but it is very well made.
I will warn you that it is alot of work getting everything fitted back up to the jeep. Cutting the holes, aligning the hood and fenders, drilling for all the bolts, etc ends up being alot of time and effort. I have a truck as a daily driver, so I can afford to take my time and do it right. The thing that bothered me in my install, was the lack of good instructions. There are alot of writeups, and I even watched the 4wdh video many times, but unless you have someone with you who has swapped a 'glass tub, you end up standing around and scratching your head alot.
If I had it to do over, I probably would go with fiberglass again, but I would definitely check out the Willys-Overland bodies that are rustproofed and already have all of the holes and nutserts in place. They started advertising these about a month after I got my body, so I didn't have a chance to research them.
