good luck with it man, i would use the 93 frame if you have the ability to shorten it.
i would have done that if i had found a 4x4 donor but i got the 2wd way to cheep to pass up.
i just bought an adaptor plate, bell housing, clutch fork, and a bolts lot from an 00 nv4500 ... ... ... now i just need the hydraulics, clutch kit and the transmission, and a few small odds and ends and the drive train will be complete.
