A: Is the size of the bore 3/4" or ? From: Marty Bricker <mbrickerusn@xxxxxxxxx> Subject: Clutch master cylinder rebuild kit To: northtexasamc@xxxxxxxxxxxxxxx, AMC List <mail@xxxxxxxxxxxx> I have an 83 SX/4 with the 5spd. My clutch master cylinder started leaking inside the car. I removed the cylinder and ordered a new one from Autozone...not even close to the correct one. Went to Partsamerica.com and found the correct one for $99. By this time I had the leaking cylinder removed and decided to take it apart. The cylinder bore is not pitted so I decided to go with a rebuild kit. One kit from Bendix only has rubber seals, anoter had a complete piston assy and the third had no picture. I went for the one with the complete piston assy and the piston is too small for the bore (going back to the website it says 11/16 bore but the others don't list a bore size so I figured it was the same for all of them). Long story to ask if anyone has a number for a correct rebuild kit. Thanks. Marty
