I bought a brake setup off a 73-79 that someone had on CL.
They did not have all the parts that we would have scavenged.

I will be getting a reman'd power booster, MC, rotors and calipers from O'Rielly's or Autozone. Anyone know if the bracket from my power drums would work with the newer setup?

Also need a proportioning valve. Suggestions?
Maybe this? Jegs/Wilwood valve

Ya better know whether it's a 73/74 or 75-79...Read this: Installing Disc Brakes on Your 2WD Pickup - Pt. 1 - FORDification.com

Do you mean the booster to firewall bracket? I used the one off my donor '78 on my 70. It fit like a flesh tuxedo.

That prop valve looks vaguely familiar... had to fab up my own bracket. Wilwood now offers one for about $32.

 

Yes, booster to firewall bracket.
You used the one from the donor truck. Was that connivence or does the drum brake bracket not fit?

 

I need to find some part # and hope they are specific the year of truck the gear came off of.

 

Sorry I dunno....I went from manual drums to power discs and had to grab everything anyway. I lucked out at the 'yard cuz there was a 70 Sport Custom right next to the 78 donor and had a chance to test fit the booster and bracket to its pedal assembly.

 

Nice... the yard I went to had no F100. 2 F250's and the rest were not dents or bumps. Need to travel further from home to see more.

 

Try the Auto Recycling Mall in Maricopa. They may still have some stuff left. 480-802-4444. And Hidden Valley Auto Parts. I don't know their number. And Boss9F100 told me there's some place out west by Bell road I believe.
