Stall ID Help

[Boz]

I bought a TCI 10" stall from a guy and was told it is a 3500 for a turbo 350-400 but only numbers I can find on it are 2421 on the front side top and 10275 on the front side bottom.

best to call TCI and ask them. just tell them you bought it years ago and forgot what it was.
