Used the brakes from a 74 SSP on my 72 Demon.
11" rotors, 11" drums. Stops excellent, great pedal feel, non-power.
Only issue I had was the banjo fitting clearance on lower control arm if using pin type calipers.
There is a pin caliper that works. I dont recall the application.
I switched the brackets to sliders since I had everything new for them.
New calipers were in the $20/side range.
