I'm not sure I understand your question. Are you going to run a standard trasmission behind a 84-85 turbo buick V6? If so, this is what you'll need: Hays 15-325 - Hays Performance Flywheels - JEGS If not, then any autoparts store can get you a new flexplate if you don't need a SFI rating. If you need and SFI rating (for racing) then call Fullthrottlespeed, they have CAT sfi flexplates.
