Folks,Clutch master cylinder leaking. How do you stop top mounting bolt from spinning under dash? I can get a 13mm closed end wrench on the bottom mounting bolt under dash, cant access top bolt. Any tips appreciated! BTW-tough to find locally DOT 3 "Non synthetic" Brake fluid. Everything is synthetic. Had to order STP brand online! Thanks again! Cliff Folks, Clutch master cylinder leaking.
