Ok stock 76 Monza calipers have same size piston as S10/Gbody.
Now the stock Monza master cylinder is 7/8 " and works fine on S10.
If you install S10 rear drums use power prake wheel cyls for power brakes, and manual brake wheel cyls for manual brakes.
Honestly I have yet to try S10 rear disc, with stock Monza master cylinder but swap out prop valve for adjustable prop valve in rear line.
My 77 had S10 front brakes, S10 rearend with maual brake wheel cylinders and stopped better than a 01 Vette, was told it was Z06 but not sure.
I am hoping my current Monza has power brakes so I'll have to swap out the rear wheel cylinders for power versions.
The stock Monza master will feed the twin piston later model S10/Blazer as its a stock replacement for older S10s or Gbodys. There is no difference.
