I got the pedal, booster and master cylinder from Mustang Steve. He sells a kit on his website.
Mach1 Driver, I remember the Booster would mooo with every push of the pedal when I did the first bleeding of the brakes, it had no vacuum hooked up.
Its a 351C stroked to a 408 the IC is 106, roller cam from Comp Cams
I have a 1969 Mustang and used the rod that drops down on the brake pedal. I believe the 1970 uses a straight rod.
I'm using a 1970 Master cyl, Dist block and 1970 front disk calibers.
