    I have a 1985 blazer with a first gen V8 and a 5 speed in it. I’m looking into a 6 speed swap. I’m looking at pulling the 6 speed transmission out of a 1991 tuned port corvette. The transmission I’m running now is a v6 new venture 3500 transmission is what i have in my blazer now. To swap in the 6 speed I know I need to get a shortened drive shaft move the transmission crossmember has to be moved back. I don’t know if I will need to swap the 3.08 gears in the axle but if I do I will. Dose anyone know if my stock flywheel and pressure plate can be used with the 6 speed?
    All info on this welcome.
