Hello guys and gals .Just bought a 1961 GMC truck and am super happy about it too! First thing I have started looking for is a brake booster to aid in stopping this monster. As it sits now it has front/rear drums,4wd,GMC 305 V-6, 4 speed. would like to know if there is a web site or any info for buying the booster. I am located in southern PA.Thanks in advance for any info or comments.
