Hi Chase,
I've built a couple CJ5s.. one ended up on coilovers and 42s before I stripped it and built a buggy.
Definately want to stretch the wheelbase. I like the 106"-108" range. Easiest way to stretch is with a link suspension and coils or coilovers (or air shocks).
Full width one ton axles. 39"+ rubber. V8, auto tranny, steep gears.
What type of budget are you working with? What type of fabrication experience/tools do you have?
What type of parts do you have available?
Lots of variables.
Hit me up anytime. I only check out Pirate about once a week or so. My email is GroundPounderFab@verizon.net
Take it easy!! Eddie
