Caliper and Master Cylinder Info

.827" seems pretty small, I don't think I'd want to go below 7/8". 15/16" works great, I really like the pedal feel with that combination. With .827" I'd be a little concerned about the amount of pedal travel, but I haven't tried it.

Also, the 2.75" piston calipers didn't just start in '76. They started on the A-body platform in '76, but all of the B/E body calipers had 2.75" pistons starting in '70.

Yes but those calipers are of a different design. That is why I specifically mentioned the A, F and M bodies. They use the same pads which mean the calipers interchange on the spindles for an easy swap. If you pull up the 10-1571 in the PDF it shows 15/16 as the bore and it is the factory MC for my 75 Duster.
