Hello, I'm new to the Jeep thing but have a love for all vintage stuff. I have a 1968 wagoneer that is beat to hell but runs good and a 1966 wagoneer with a good body and no engine. Want to swap my engine and tranny into the '66. I was wondering about it's axles though. The back has a center nut (tapered axle) and the front locking hubs look a little wimpy. Any issues with these older style axles? Would I be better off swapping the axles of the '68 as well? Any input would be appreciated. I don't want a crazy rock crawler just a reliable rig for the mountains.
