Doug, you mentioned in a different thread that 67 Tbird rotors were used by some of the upgrade factory race cars? I believe you said they were 12" vented rotors front and rear that fit the stock spindles along with an F250 master cylinder? What calipers were used?
Do you have anymore details?
The front calipers are the same as the rotors. They are really generic "big Ford" and you will find them listed as 65-69 T-bird, Galaxie, or Lincoln.
The rear calipers on the race cars are different. I'm using a different set up then that on the rear of my beast. I put in an "upgraded" Lincoln Versalles rear.
The rotors are also now "generic". They are only nominally 12" and actually measure 11.75od x 1.25" thick.
The serious racers don't bother with them and use race rotors and hats that sit on the outside of the hub for faster servicing at the track.
The master I'm using was a Ford Service part I got around '75. It is bigger then the Mustang unit and you need to grind it to fit against the shock tower.
You also may not like the hardness of the pedal it gives you. The piston is 1-5/16".
I can't find the cross reference to it with the stamping number on the housing. It comes up a blank, but I was told it was for something like a '70 F250 with manual brakes. A strange beast.
