I have a 71 CJ-6. It is down to the frame right now. It is waiting for me to finish the CJ-8 I'm working on now. I think that I will get radical with the CJ-6. Full length axles, maybe Warn coil spring set up. Probably a V-8. It will be fun!
I just traded an old fishing boat for a pretty nice 75 CJ-6. I also just purchased a 78 Wag with a donor 401 and auto trans to swap in it to start what I'm sure will end up as a powerful tool in the war against dirt.
