Thanks guys. I talked to Buffalo yesterday & he is currently using the 5 speed from a S10 2wd & the rear from a 4x4 S10. Tranny needs to have mechanical speedo output which puts it back into the 80's. Opt for the 3.76 first gear as the 4.03 is a bit too low (1985/1986 vintage). The 3.73 rear is recommended. Need to reuse 216 bellhousing, flywheel & starter as the later bellhousing will put a bind on existing clutch linkage because of the exit angle of the actuator lever (also provides for rear mount). Will need to fab up a tranny mount using 2 pieces of angle & an aluminum spacer. X-Member will need to be torched for this. Before I go off and search for parts, does anyone know if their are any open drive Chevy manuals (3 or 4 speed) that I could use without cutting up the cross member? I pretty sure I can locate a 57 rear. I'm trying to do this swap out as painless as possible. Thanks! Sherman
