GM part # 3899621 Bellhousing
This is a nice used original part.. This particular 168 tooth clutch housing has been lightly bead blasted to clean and check for flaws. All threads have been chased. The 1/2" threads have the typical casting void in one of them and show some wear, but are still tight. There are no cracks, welds or modifications present.
This one has the threaded hole for the 1965-70 Chevrolet B bodies (Impala).
To use any 621 bellhousing, you must have a cast iron nose starter that looks like this
