Most any master cylinder from the late 1960's to the mid 1970's will bolt on, just make sure it is for a DISC BRAKE car. In the late 1970's or thereabouts they went with an aluminum/plastic master cylinder. Any of these will work, as long as you buy an adapter from a vendor such as AR Engineering. These masters use a two bolt mount, and they adapter fixes this AND positions the newer master so that you don't need to change or adjust your current brake rod. The newer masters don't look right, but I love 'em. You can see your fluid level, and the spin on caps are a treat. Finally, if you are going to use manual disc brakes, get a master for MANUAL disc brakes. Otherwise, the pedal pressure might be very stiff. ---- Please address private mail -- mail of interest to only one person -- directly to that person.
