I need info on Flywheel and Bellhousing Specs for a 1969 Mustang. I'm changing from a 3 speed to an automatic (c4) the person I bought the tranny from also gave me a TCI Torque Converter with a 10 1/2 bolt pattern. The diameter of the old flywheel(3 speed) was 14 1/4. So my question is is ther e such a flywheel as a 14 1/4 diameter with a 10 1/2 inch bolt pattern?

Not that I am aware of.

You will want to get a 157 tooth flexplate and matching bell housing. You should be able to pick up the flexplate for about 60-75 dollars. As for the bell housing, good luck /forums/images/icons/smile.gif

I think that NPD carries the flexplate you are looking for.

Oh, there is also the 164 tooth option which I think is an 11.4" bolt pattern (used for large blocks?). You will need a different bell housing to support this option.
