Factory power brakes were available on the '63-'66 Chevy trucks, so now worries on finding a direct bolt-in power brake booster assembly. I have done this conversion many times on my 4-5-6 Chevy trucks, as well as, several customer's trucks. Let me know if you need tech support or parts for a factory power brake conversion, utilizing factory power brake components. The conversion can be done in a few hours and does not require breaking into the system or bleeding the brakes, if you keep drums on all four corners.
