Works for 1995 honda civic
Fits great on my 1995 honda civic. Old one was leaking onto the clutch pedal. Replaced it with this and now no more leaks.

The size of the clutch line is too small doesn’t fit and no one makes an adapter

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.

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!
