I have a 70 C10 with factory power brakes and a classic perfomance front disc brake conversion kit. Time has to replace my master cylinder and booster and I'm not sure what I need. I bought the truck with the kit on it so without thinking I just bought the booster/mc for my year truck, which obviously didnt work with my setup. The booster was much thinner and would not work with my firewall brackets or under dash linkages, I had no pedal movement. What do I do?
