Hello Camaro Guru's,
I am in the process of converting my '69's four wheel drum brakes to C4 Corvette discs, and I want to use the 1988 S10 Master Cylinder. The problem is there are two S10 Master Cylinders for manual brakes a JB-1 or a JB-3. What does this code stand for and which one should I use??? Your help is appreiated.
