Thanks for the response to my question with regards to replacing the clutch master cylinder in my gals 93 yj. You stated that recently you replaced your clutch m/c, I have one additional question for you. Every clutch m/c i've seen has a threaded port for the hydraulic line that supplies the slave cylinder. My gals jeep has the same set up as yours with the pin and don't believe these clutch m/c will not work without some sort of mod to the hydraulic hose/line or puchasing a new line with the mating fitting. The replacement p/n I've been seeing is 4636865, is this the same p/n that you replaced your clutch m/c with? Regards, Frank
