Ebay. Not mine. Decent price, considering availability of genuine GM parts. It's genuine GM part according to the information on the back. The repro does not have a number after the "DOTT" and on the repro, the part number spacing between the numbers is closer together. Based on this, this is an original. Up to you. Repros are 1/2 this price, and this is a good price if it is indeed, never used. So if you just have to have NOS GM, this should work. Check it out close.
