ok, i got an exedy (was told it was something else before I bought it) clutch, bearing, pressure plate for a 90-91 crx and I have an 89 model (i was told it would fit, and didn't know the difference)
my question is, should i try to get a different disk (since this one is 12mm too big) or should i just sell this one and get one for an 89? what do you guys think?

 

try a flywheel for a 90+

 

The bolts for the Pressure plate will be in slightly a different spot on the 88/89 Flywheel opposed to the 90-91. (since its larger)

So yes, get a newer flywheel
