Thanks John
Yes the tailhousing had the bearing release access plate on the side of the tailhousing. I was hoping it was a small block piece to use the main case only. Darn |

Quickest way I've found to ID a big block/small block bellhousing is to measure the distance between the top transmission-to-engine mount bolt holes.
The big block bellhousing hass about 6-3/8" between top holes. Not sure what the small block number is but it's more than that; probably 9 or 10 inches or so. |

No need to measure, just eyeball the bottom four bolt holes on the bellhousing. BB has four equal sized holes, SB has two small and two larger.
