I have a 94 civ with a 96 gsr engine swapped in. My clutch master cylinder is leaking / needs to be replaced and i'm not sure if i need to get an integra, or a civic CMC to replace it.

Master cylinder is a Nissin & has "5/8" on it

 

Both civic and integra clutch master cylinders are the same I believe it should not matter.

 

Yep, both are exactly the same.

 

Chill! Thanks guys, i'll get to ordering it
