ZCHF

ok guys, i've been looking for the right clutch i need to put into my zc tranny. i have gotten different views but does anyone know what really works? Right now i have a 89 crx clutch and a 86-89 integra clutch. I was told that i needed the crx disc and the integ pressure plate. Does anyone know whats right, because i would like to know what is correct before i rip into my clutch. thanks
oh yeah, how long would it take a first time clutch changer to do this . thanks again
