Re: Brake pedal issue after conversion to power assist from manual on 1969

-
I have changed 3 trucks over from manual to power brakes and never had to change wheel cylinders or re-drill a pedal arm. I have always used stock boosters so there could be a difference in the 8.5 inch dual booster. I have also always used the port in the rear of the intake manifold instead of the back of the carb. On my White '67 SWB I even used the manual master cylinder with no problems. I didn't even unhook the lines when I installed the booster, just unbolted it from the firewall, pulled it back, and bolted it to the booster after it was installed. I know I changed the master cyl to booster rod.
