there were several variations. gm, ford, amc, Studebaker, and mopar had there own variants. some internals may interchange but gear ratios are different between gm, ford and mopar. I know the inputs are different between them. I think what you have is ideal for the collector/restorer; especially mopar, and may be worth something on a trade in with one of the mopar 4spd vendors. ask some questions with vendors or collectors before you start cutting parts up.

the t10 is basically the t85 with and extra forward gear in the main case and reverse in the tail. the t85 was supposed to be stronger. neither are up to modern performance standards.
