Here is are the links to the T-150 & T-176... Sounds like you might have a T-150 Bellhousing...

If the bellhousing that you have is roughly 6" deep with a 4 hole bolt pattern (tranny side) that measures 8 1/2" wide by 6 5/16" Tall (Ford "Butterfly" pattern) I'd be interested if the price is right.
