How about an s-10 frame? Its small and about the same size as the car its self. i know it may sound noob and dumb but I have herd the s-10 frame being used in alot of custome rides. Im sure you could find a decent frame from a j/y that isnt fubr and pull the cab and bed off if it isnt done already. I just see alot of cars that are out of this world and if these ppl put that kind of money into there ride Id assume anything is possible..
Yep, ppl do use s-10 frames. My lil bro used one to build a RatRod.
