Speaking of verifying, I need to verify the info I have is correct.

I've got a Tremec Aftermarket T56 which was designed by Borg Warner to be a replacement for the F-body T5 before all the TKO's and such came about. It bolts to the same bell that fits an f-body T5. I believe these are also the same as the Muncie 4 speed bells, correct?

Is the stock 66 C10 (6 cyl motor currently) bellhousing center hole the same as both these other bells? I think I read the other 4 attaching bolt holes are the same. I know the 6 cyl bell will also fit the small block engines.

If so, then my aftermarket T56 should just bolt right in. I do plan on removing the bellhousing crossmember using just the bell and adding a rear crossmember due to the added weight (at least 150 lbs) of the T56.

Here's a couple pics of what I have.

Thanks for any clarification.
