This is a series 3 carrier with a 3.91 gear set. It has been sitting in my shop for years. The receipt for the new crush washer is dated 1986! It was cleaned up but now has surface rust from sitting. Included is 2 new gm crush washers, a new gm pinion nut and bearings (not sure if its a complete set). There is a couple of broken clutch plates so a new clutch pack would be needed. Offers on $200. Email or text 250-436-0102. Located in Chemainus. Cleaning shop check out my other listings.
