Perfect fit but installation may be difficult
The master cylinder fit my 1998 civic perfectly. If (like me) you're not a mechanic, be prepared. The actual installation is very simple. Removing and reattaching the cotter-pin to the clutch pedal may take some time. This is no fault of the master cylinder part. The attachment point to the clutch pedal is in a very awkward position. It requires you to lie on your back at an angle. FYI, as the area is so high up under the steering wheel side of the dash, a good light source will come in handy. I also used my smart phone to record video to locate the exact position of the cotter-pin for removal and installation, as it is difficult to see. Despite my installation difficulties, this is a great deal for the Do-it-yourself folks!

Doesn't fit.
Just received it today and tried to install and the thread size for the brake line nut was incorrect. The OEM master had a larger nut than this new replacement. Item does seem like it could be of quality but annoying having to deal with some trivial differences in parts.
