It has the 4 11/16 bore for the bearing retainer. It is designed for the 10 1/2 Clutch.

This bellhousing has been degreased and left in the original finish. It has not been sandblasted as some would prefer. All threads have been checked and are in good condition. There is the typical casting flash and minor knicks and marks you would expect with a used bellhousing. The casting flash has not been removed for those purists who want it in as original condition possible. Because some people mistake casting flash as cracks we have inspected and verified there are no cracks. 

This item will ship in 22 x 22 x 8-inch box with plenty of cushion to avoid damage during shipping
