i have a 89 civic hatch and my throwout bearing is bad...but the clutch is still good my question is if i were to get a new clutch 90-91 do i have to get a 90-91 flywheel too since the 89 flywheel is smaller or can i keep the flywheel i have in there now and just use it..also is a 90-91 clutch better than getting a regular 89 clutch or its about the same?
