This unit is NOS in gm box. However, there is no part number on the box, the box has deteriorated. This unit still has the foam packing and is in great shape but the fitment isn’t listed. I do know the car this was purchased for was a 1976 Cutlass Supreme, but again there is no evidence to support it. It is sold as is and will go greatly for someone’s cutlass! Please match your parts before purchasing. Sold as is with no returns. Thanks for looking! BR1
