73-87 Power booster Mod to fit our trucks ?
I don' have a original booter for a C10 and I don't like the way that the original one looks. So do you see any reason I could'nt use a newer one? I may have to make a longer push rod and drill/ fill some holes but no biggie. I am in the paint and body work process now so I can weld and drill all I want.
Thanks Mario ![]()

I've got one from a newer truck (80's) and have been fitting it to the cab im working on. It's no big deal from what I can see. The bracket for the booster needs 2 additional holes drilled and I plan on cutting off the top portion of the bracket (the old 2 holes that aren't used). Then you'll need to make a longer push rod (about 3 inches longer I'm guessing).

You guys might try a search, I seem to remember seeing some good info concerning this mod in the past. This is one of those topics that we need a good, informative, article on, and then have it included in the FAQ section.

Okay, it's been awhile since I had a '77 booster on mine, but I remember that I used a coupler nut to lengthen the rod and I had to drill 2 extra holes where it mounted to the firewall.

or you can always do the next best thing which I will be doing, just take the brake pedal off of the 73 - UP truck and remove the old one from our trucks (67 - 72) and just put the proportioning valve in the same spot as the 73 - UP... I plan on going this route since I am going to be swapping front Suspension from my 74 C10 to my 68 (so I can get the newer motor mounts and disc front setup), and I am just going to use the newer brake booster and master cyl.. other then that should not be too tough...
