1978-1987 Regal Chevrolet 4 Speed Bell Housing 621 Replacement Style FBH-11

This 1978-1987 Regal Chevrolet 4-speed manual transmission bellhousing is a high-quality replacement for the GM 621 aluminum bellhousing, designed to fit most small-block and big-block Chevy applications using a 168-tooth flywheel and a Muncie or Saginaw transmission. Made from durable cast aluminum, it features precision-machined mating surfaces for a secure, accurate fit and a clean sandblasted finish that closely resembles the original factory appearance. This reproduction does not include any casting numbers and lacks the upper rear mounting hole found on truck-specific applications.

Manufacturer Part Number : FBH-11

Part Notes:

Our clutch fork pivot ball FTE-9000 will fit but may require the bell housing threads to be tapped/chased and or brushed with an emory cloth to fit properly. This bell housing is not compatible with 1962-1967 II & Nova models as the size of the transmission tunnel is too narrow.
