help with my clutch

hey anyone i have a 91 honda civic hb but not sure about if it's DX.SI.an so on......So i cant fine the clutch i need.....they said that my old clutch is 7 7/8 3/4 shaft 21 spune on my block it says ZC...plzzzzz hlep me get my car going t/y

Is it a dohc ZC? In other words, does the engine have 2 cams? (spark plugs in the middle of the valve cover) or is a sohc zc ie. 1 cam and spark plugs closer to firewall? Either way, you have a swap because usdm civic never came with zc. Do you have an electronic sunroof? If so, it's an si. It sounds like you need a 91 clutch. We need more info though. Clutches were different in 88 and 89 I believe the spline count differed.

it's a sohc ZC cuz it only have 1 cam.........do it dont have a electronic sunroof....i tryed the 91 clutch.....what else do you need to know just ask...o do you think the integra 86-89 clutch well go on ?

if it has a swap then it dont matter if your car is a dx si lx or whatever all that matters is what engine and trans is in it cause thats how your gonna order the clutch. if its a single cam zc then no integra clutch will not work has a diffrent input shaft diameter. u need to know what trans u have whats the number on the trans? cause a dx an si trans are completely diffrent.

dx and si clutches are the same for a 91... i have both the clutch for the si is the same for the dx...
if you have the "zc tranny" i dont know if they are any diffrent
