I want to get a harder, firmer brake pedal. Which master cylinder is going to accomplish this: the larger bore, or the smaller bore?
Car in question is a 1968 B-Body with front discs, rear drums, and an aluminum late model MC with a 1 1/16" bore (1.063").
A MC from a 1995 Dakota has a 15/16" bore. Will using this MC provide for a harder pedal? Will it even bolt up correctly?

Thanks guys.
