Thinking of converting to Manual Brakes

Read that I should probably swap to a manual Master Cylinder also because it has a bigger piston and wouldnt have such a hard pedal feel. Problem is Im not sure what MC would work with my car. I have front disc and rear drums. Also does anyone have a manual push rod they could part with?

No, the bigger piston will create a harder pedal. Mopar put the "soft" pedal small piston MC on the power brake cars -- who knows why? Most people seem to like the small piston converted to manual. I can vouch that the factory manual disks require serious pedal effort.

All the disk brake MCs are interchangeable -- A, B, E -- you just want to look at the bore sizes.
