Jim, I did somthing very similar to what you're talking about with the white 70 Javelin when I converted it from power drums to power front discs. I ended up using some nuts as spacers, and I can't remember where the push rod came from, but yeah it worked for me in my application.

I have a 75 Gremlin with manual drum brakes. I know that the master cylinder for drum brakes is different from the one for disk brakes. I checked and verified that the master cylnder for manual disk brakes and for power disk brakes are the same. My question before was about the pushrod which connects the pedal to the cylinder. Now, I am thinking about moving the booster over to the Gremlin, push rod and all, and to use the push rod from the Gremlin, as well as the little mounting plate which holds the cylinder to the firewall in the Gremlin, over to the Concord. Does this look like something which would work? Keep Ramblin!
