Installing power brake booster - help??

[marts213]

Hey everyone. I just picked up a 69 c10 back in September. The truck came with manual drums and I just installed a disc brake kit (McGaugheys drop spindles) along with 1" drop springs from ECE. (Brake kit was purchased from Auto City Classic, Inc) . Everything was going along fine until trying to install the power booster. The rod that's coming out of the booster only goes through the firewall so much. It's about 4-5 inches short of the brake pedal. Is there a different brake pedal for power brakes vs. manual brakes? If so, can I use one from a later model pickup? Or do I have to use part of the old rod that I removed? Let me know if I'm not being clear enough about anything. Thanks.

Mike
