I am building a street/strip 1994 Firebird. I will install a 350 turbo transmission, 3500 stall and want to try to keep my 7.5, 10 bolts differential with 4.10 gear but I cannot find a company that make a Spool.
Could you help me?

Charles Mamano,
The 7.5 is a very small differential and not too strong to start with. We are checking into it, but I don’t think a company would spend the time and effort to do that on such a weak differential.

Thanks, Mike.
