Used OEM Casting #3858403 153 Tooth Bellhousing.
This part number is listed for and used on almost all 3 or 4 speed Chevrolet engines with a 10.4" (10 1/2") clutch from 1964 to at least 1978.
This particular bellhousing is dirty, but will clean up nice. The 1/2'' (transmission mounting) and 1/4" (inspection plate mounting) threads have been chased, all are good.
This housing has the pilot hole, that will need to be tapped for 1965-70 Chevrolet fullsize cars.
There are no cracks, welds, modifications or stripped holes.
This Clutch Housing will not fit 168 tooth flywheels.
This is a limited stock item. Pictures and description are of actual part.
