Your signature says "73-87 front suspension w/Disc". The '76 had a brake, Combination Valve mounted on the crossmember under the radiator. If you don't have the Combination valve, did they include a stand-alone proportioning valve on the rear brake line? I can see a distribution block/brake light switch in your pictures.
Your signature also says, " ??? Cam". Unless you have really weak manifold vacuum, I'd loose that huge vacuum reservoir canister.

I'm just learning exactly what front suspension and MC I have. That's what prompted this thread. When I got the truck I learned that the front end was from a later model. It may not be the complete front suspension, but pieces such as the lower and upper control arms and disc. I just became aware of the proportioning valve for the 73-87 was located on the front crossmember. Since mine is located below the MC it made me wonder how much of the front suspension is stock to 1970 and how much of it is 73-87. My soft brake line attachment is located to the rear of the upper control arm. I think that's we're the 1970 hard line ends. 1971 & 1972 hard line ends in front of the UPC. The 73-87 hard line come through the frame. I need to buy shorter soft lines.
I like the brake booster with out the braket....doesn't stick out as far, but not crazy about the MC slant nose.
As far as the brake booster auxiliary vacuum tank. I didn't like the feel of the brake pedal..low vacuum driven by the ???cam, so I added it. Seems to have helped, better feel.
Thanks for your input on the MC & Booster
