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?
And forget about vette versions. It’s simply not possible. The vette version has a unique midplate as well as an included transaxle. It’s too short for a Mopar to as is and converting costs more than buying one that will bolt in
