This Ford differential cover is on special because it has some blemishes in the finish and it does not have fill or level check holes or a boss that can optionally be machined for a temperature sending unit. This cover was made for vehicles that use the level check and fill on the carrier.
For reference, see our regular Ford 8.8 Straight Fins Rear Differential Cover, PML Part Number 7064.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
Note that the polish finish has some imperfections, including porosity between fins 3 and 4.
