'88 civic hatch 4spd

i'm hoping someone out there can help me... I have a '88 civic hatch with a 4spd manual transmission... I need to know how many splines are on the input shaft...

I'm going to move this into the 4th gen section for you. It's better placed there.

IIRC, it's 28.. it's the wierd one in the family, not b/c it's a 4 speed, but b/c it's an 88.. we had this problem with my car... ended up using an 89 transaxle with a 89 clutch disk, and a 88 pressure plate... but yeah, if you want to verify, good place to look would be www.rockauto.com that's where I get most of my info for replacing/ratting parts together.
