I see two different clutch master cylinders listed, one for early cars and one I believe for 91-92 cars. My questions is, I'm doing a 5spd swap on my 92 car, but the pedals and full conversion came from an 87 car, so which will I need? I'm not real sure on the difference and I cant find anything to tell me, so I just want to be sure before I buy a new one. Thanks in advance guys.
