I would do up an old Willys Jeep wagon. lift it, stick some SBC mounts in it which are readilly available for that swap I'm pretty sure, then you could do a mechanical GM 6.2/ 6.5L Diesel pretty easy ( std chevy bell and uses SBC mounts )... that will give you a solid axle 4x4, seating for 5 or more and removable front fenders. you could change it all up and make it look entirely diffrent.. I saw a '95 Wrangler with a '33 Ford grille grafted in, correct looking fenders and headlights mounted to a bar. actually looked pretty good. and it was still EFI, 4.0L 5spd. they didn't do anything to the interior to make it look 30's which took some away, but it was still pretty cool
