88 Crx clutch problems

[draybook]

I am in need of a clutch for my 91 CRX but I have a few problems. First, the 91 clutch doesn't fit on it. I have a ZC motor in it, I think it's an 89 or 88 motor, DOHC. The tranny is an 88.

I have measured the clutch and disc/pressure plate that came off of my car and here are the dimensions:

It's a 21 spline clutch.
Clutch disc is roughly 8 3/8ths inches
Pressure plate is 10 inches in diameter.

Now, I measured from end to end on each item so I guess I measured them correctly.

I'm thinking that perhaps I need an 88 clutch and 88 pressure plate but with a 91 disc, since the 91 disc is about the right size.

If anyone can help it would be appreciated.
