[Brysenj]

I'm going to finally get my 1970 c10 "the gold truck" running it had a 307 and 3 speed in it original drive train I'm going to put in a 305 and 4 speed out of a 1968 gmc is anything different it's floor shift I know the shifter but what about motor mounts and transmission crosmember .

Make sure you get the high hump floor plate, your going to have to cut out your floor. Take the complete drive shaft from the donor truck and the center bearing frame bracket that is riveted to the frame. The 305 is that a v8 or a gmc v6.

The truck it's going in is a long bed and the one that the engine is coming out of is a short bed , v6
