The better ones are made by warrior. They are prefabed to your year jeep. They are good for cover up but can trap moisture making a rust prob worst. Because most are alum you won't see the prob until your quarter panel falls off. I would do the BW first then add for protection.
I have a 'glass/kevlar body from when AJ's was still around. My frame was shot('79). So, I'm going widetrack, since it came w/ the 44 rear. Even though I love the NT look. I'm doing a frame up w/an '86 also. I'm keeping the 30 up front...until it breaks. A 30 can be built to take a beating w/ the right parts. Hunt for a 44 in the meantime, but get out & enjoy it w/o worries.
Yeah I have decide to trail ride it soon and if the AMC 20 or Dana 30 or SR4 fail. I am replacing them anyway. I got invited to trail ride with some local Jeepers this Sat. Gonna see if I can fit that in.
I ended up buying a Dana 44 front and a 14 bolt rear from a 3/4 ton Chevy. They are beling delivered to my house by the guy. I got the axles and a T18 tranny for $500 delivered. Then another $100 for the rims. Glad I found thiss guy he has got a ton of CJ-7 stuff, he is local, and he delivers!
Like everyone else is saying you lose a good amount of ground clearance with those axles and only 33s. I'm aware your axles have already been bought but you should really look into getting bigger tires if you intent to do any serious crawling.
How tall is your garage door opening? Unless your Jeep is staying outside, it might be a factor. Nothing like wrenching in a dry garage. With 35 to 38 inch tires a gear swap will probably be in order unless you got lucky. See what you've got and maybe you can save that expense. A bit more lift or extensive trimming may also be required.
