OEM Supra/Chaser/Crown Rear Driveshaft Axle Washer.
This is one of the bolts to connect the driveshaft to your differential.
Note: This product does not come in the OEM Toyota packaging, as Toyota doesn't sell this item usually individually. This is for a single bolt.
Six of these are required for each driveshaft and a total of twelve for one vehicle.
*Check late model Supras as they use a different bolt*
