Re: 20, 21 spline? transmision question (91HATCH)
i think the 21 spline is the 88 si trannys that has a smaller clutch disc and i think the 20 splines is for 89-91 si trannys.

im sure this is right infromation on what i said. i looked it up. i suggest you use the 20 spline, because you got a 91 hatch.
