Added Factory Brake Booster to 1970 C/10 Now Brake Pedal Sits Low

[cericd]

I have a 1970 C/10 that came with manual 4-wheel drum brakes and 3 OTT transmission. I recently converted the front to disc brakes and added a factory Delco/Moraine 1/2 ton booster from a 1971 C/10 and I can't get the brake pedal to be even with the clutch pedal.

I am using what I believe to be the factory booster brackets and push rod but there doesn't seem to be a way to adjust the brake pedal to the correct position. I've searched but can't find a solution to this issue on the forum. I guess most people don't keep a standard transmission when adding a brake booster. I did see that there are issues with the mounting hole in the brake pedal lever seeming to be in the wrong position for correct linkage geometry.

Were there different brake pedals for trucks with boosters or for trucks with disc brakes?

Someone must have encountered this issue before. Any insight is appreciated.
