Have you considered a Scrambler. They're like a CJ7 with real wheelbase. They're easier to fit in a bigger motor and transmission and still have room for a driveshaft. You can leave the body full length and have some real room or shorten the bed to get a better departure angle. And they're fairly rare which is cool.
'86 CJ7, 258 w/Mopar MPI, 4.56 gears, rear Detroit/front Truetrac, full cage, OBA, 8274, 4" lift via Alcans/Rancho, 35's on beadlocks, other stuff. Built for rocks, mud is a four letter word.
