Ok, I've searched and read but nowhere can I find info relating to my problem. Here goes, I ordered and received a master booster combo for my 1971 C10 so I could convert it to power brakes. It will not mount without "something" else. It will take either some kind of bracket or major modification to the firewall. There are 4 studs coming through the firewall from the pedal cluster inside the cab under the dash. The old non-power master is centered on and mounts to the bottom pair. The hole for the brake rod is between them. The new master/booster also has 4 studs equally spaced around a center rod and hole. See the problem? Has anyone run into this before?
Everyone seems to sell the same master/booster combo for a 1971, even down to using the same part number!
I have got to be missing something, either in my head or on my truck!
I thought it was supposed to be almost a bolt-on to do power brakes on the 1971s. What have I done wrong?
Any suggestions or help will greatly appreciated!
best wishes,
Les
