First of all, I was just tellin' a buddy how much I like the looks of a CJ6. The new JP magazine has a project CJ6 they're deciding how to build it. They're not that common, didn't make very many. That being said, that top wouldn't be easy to come by i'd definitely fix it if it were me. I may be wrong but i don't think they make a fiberglass tub for a 6, if they do I haven't seen it. Jeeps aren't bad when it comes to body repair. Be sure to use shileding gas like 75/25 argon mix and not flux core wire when welding in the pannels. Flux gets trapped in the weld and causes rust, it also takes more amperage to weld with flux core, therfore more heat which leads to warpage in the pannel. You can get replacement pannels from Quadratech, 4wd hardware, J.C. Whitney, ebay it'd be cheaper and easier to buy 'em made than buy sheet metal and try to make 'em. Plus you'll save a ton of time. Good looking Jeep you got there, good luck with it.
