Hey guys,
Need a fast answer I hope...
Tried a quick search and could not find the answer. Getting ready to buy a torque converter (online auction) and need a quick answer. I am adding a 69 455 and a 69 th400 to my 72. The converter is a TCI saturday night special. One guy at TCI says it will fit and another says it depends on the flex plate pattern and if it is a "small" or "large" pattern. TCI Part 241500

I am at work and the auction end in a couple hours. How do I know what flex plate pattern I have? or if this will fit?

I believe this is a Chevy TC, you need one that is a BPO.

So the guys at tci are incorrect? Are there different patterns on olds flex plates?
