Internal balanced..what damper do I need

Whoops I left out some info I forgot to mention the scat kit is internal balanced from them.my torque convertor is a tci super street fighter 142222. I'm using a sfi (forgot the brand name)flex plate for internal balanced. ..well I just messaged a friend who works at my engine builder and he is looking into what damper they used.. To me it looks like a stock damper.
Ive done some research since starting this thread and have found lots of answers I was looking for, hopefully will find the problem soon.
