Default TCI flywheel 399753 not working.....

I just got in my new TCI flywheel in and it does NOT line up with my 350 converter bolt holes at all. It has two patterns on it but they are both to small. Anyone else having this problem?

you would need the one for the 4L80E trans then, it's the 399754 IIRC. or search on summit and it'll pop up I'm sure.

Yea, I bought the 399753 and it will not bolt up to my converter. I guess it will if I take a grinder to it but I really dont want to do that to my brand new $220 flywheel. I thought it was supposed to work with the old 350 converters. Haha not mine!
