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.

Well I ran the part number for that TC, nowhere does it say it has external balance weights. If you look at the front of the damper does the outer hub section have a recessed part that goes roughly half-way around, or is it smooth and the same thickness all the way around?
