Quoting Boos929:
Going to order a new act street disc and I'm wondering what spline quantity my car is or if it makes a difference says 20 spline or 24 spline and both say that they go my car which is a mostly stock 92 gvr4
I don't know who you're ordering from, but i'd think twice about it if they're asking how many "splines" your input shaft has. This is a question i have never come across in over a decade of replacing clutches.. and having worked at a clutch shop that did a lot of mitsus, that's a whooooole lotta clutches.
