1978 dodge power wagon short bed 4x4

well you prolly can buy them and weld them in on a 60s dart lol. i really dont know wat im gonna do yet im still debating the whole 4 spd 5 spd swap, i really wanna do another cab a redo the wiring but then againt i wanan keep going, either way watever i do with it will be cool either in teh near future or eventually. if i strip the truck ill keep the cool **** off of it, the drive train the seats and all that anybody got any good wiring companies? i got american auto wire and there was another one i had in mind the wiring is just a rats nest, and i think a new clean kit will be alot less wires too and yeah itll be a pain but maybe i can add a few things without having to tap **** in, like say power windows? my radio, my tach and the off road lights
