I had an alumnium mopar MC 1 1/32" and i just have replaced it for a 15/16" cast iron Dorman unit (73-76 A body)
I haven,t run the car yet, but at least the effort and the pressure on the front calipers are the same as the 1 1/32 mc.
1500 psi with both MCs ,pressing the pedal with all my force(manual brakes)
