The body and bed on my 4wd 2001(actually a GMC Sonoma) are getting pretty rusted out. Some of the fiberglass kit cars I see advertise as being able to be placed on an S10 chassis, but they usually always say not 4wd, only 2wd. Just curious if anyone know what it is about the 4wd chassis that makes them incompatible with the kit cars. I was speculating it was the transfer case(bump in floor?) or maybe the torsion bar front suspension(interferes with the rockers?) but I'm just guessing.
