MANUAL TO POWER
To get this sled stopping like it should, or at least to modern-day standards, we also ordered Master Power's booster and master cylinder kit. First, we loosened the four 9/16 nuts that held in the original manual master cylinder and pried it away from the firewall. In our case, the piston rod that ran through the firewall to the pedal fell out. Next, we disconnected the stock piston rod fork from the stock pedal location by pushing out the stock pin. Master Power even supplied us with a new one so we could toss the original piece.
