Got a '90-'91 Exedy clutch kit and flywheel for my '89 civic hb, ( ~12% more clutch surface area). Assembled, and find to much distance between the release bearing and pressure plate release levers. Bellcrank arm now has to travel halfway up before engagement. I'm thinking that the release levers are not at as much of an angle as the stock ones. Thats about the only thing I didn't check before installation. Exedy suggests this swap in their catalouge, but are of no assistance, relating only that their parts are perfect and flawless.
