Any differance in B-series flywheels? I don't mean weight...i mean clutch plate bolt pattern?

I have ordered 2 clutches from NAPA for a 91' LS integra b18a1, Both pressure plates where bigger than the damn flywheel?


The flywheel is of my old b18a1, now on a b18b...its an ACT flywheel.

 

I am playing hell with this....These damn people are nuts. 90-01 has a 8 5/8 disc, with exception of 93 which is 8 7/8.

These people are trying to tell me....i have the wrong flywheel. Now i am out 35$ for the overnight shipping (they won't refund) and I still don't have the right fucking clutch....They have a 9" pressure plate listed for all b18's...fuckers. (for rmfd)
