T56 Conversion

I had misread the info, I was thinking spline count not gear teeth like you said, any way known to hunt out which vehicles had 31 tooth setup, maybe 94-97 vetts, trans ams, and SS camaros?
All GM T56s had the 31 tooth except for one year, 1993, EARLY 1993. They are rarer.

Best bet if you’re sourcing one from GM car is a 98+ with the LS engine. Otherwise, no one makes a bell to fit the LT1 versions of the 94-97
