it is the 153 tooth flywheel. My starter died (a proform performance starter from jegs.) Why pay $150 for another when autozone has them for $60. If I have to repace it again its free. anyways, they do things by car year and of course the car, a 72 corvette stingray had a 168 tooth flywheel. wrong part number. Any help whould be nice. I've done a search and nothing. Thank you.

 

You have a sb, right?
I would guess that a starter for any year sb would work fine. I don't think the sb's came with a 168 tooth, only the bb's. Pick a year that had the sb, and go from there.
