Master Cylinder question.

Six years since the last post... got to be some kind of record :D

While we're here though, Autozone and others show the manual m/c has a 1-1/16" bore but the power m/c is 15/16"? Would have thought it'd be the other way round, but that seems to be consistent over several store sites.

So could I use the power (15/16") m/c with a manual pedal and pushrod?
