Here's my rig. '57 CJ-5 on a shortened and narrowed YJ frame.
Rubicon Express 4.5" YJ springs, SUA
Chevy 327 with TPI
Dana 18 t-case
Dana 44's. ARB front. Detroit and full floater rear.
It's a pretty basic rig but it suits me well. Mostly designed to hold up good on the trail but still handle a little street driving. Here are a couple pics. I'll post up some better ones if I can find them.
