So I drove up to Marble Falls and bought up my power disk brake conversion kit. My 70 has manual drums on all four. I’m keeping the rear drums and just doing front disc and booster combo. Im going to have to remove the front seat and partially dismantle the dash just to make it easier to access. I’m capable of doing it since it hasn’t been the first time I’ve stripped the car down. Any pointers in the install? Any tricks to getting the proportioning valve adjusted right? Thanks in advance.
