i am wondering if the input shaft has the same spline size as a 94 and up tranny
i know they have "hydro" internals and you can use a 94+ lsd in it but i am curious if the splines are the same

 

For the one millionth time, all 1992-01 B-series transmissions have a 26mm input shaft diameter.

All hydro components go right into the 92-93 YS1s, and diffs fit with some slight grinding to the tranny case...

 

Yes it does. G2 and earler G3 GSRs use the same clutch (same part #). The part # for the mainshaft itself differs in the hydro GSR transmissions, but I can't easily tell the difference when they're on the bench next to each other.

 

ok thanks that is all i wanted to know
