This part is special because of the excessive porosity all over the cover.
Porosity is little pinprick holes that occur naturally during the sand casting process. This cover has more than normal that became visible when the cover was polished.
For reference, see our regular PML Rear Differential Cover for American Axle 11 1/2 inch (292mm) Ring Gear, 14 Bolts, Polished finish, PML Part Number 11147.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
