I think the stock crossmember and drive shaft will work if you use a Aod which is stock auto tranny for those cars but if you go with a C4 which most people do for racing and higher horsepower levels, you might have to fab one up and get a yoke conversion.
As far as the stock console like I said before if you use the stock auto tranny everything from the donor car should bolt up.
Goodluck, Charles
