Opinions welcome

Don't plan on changing the master cylinder. Brake lines will probably all get swapped out. Got new flex hoses, so I'll do the lines as well. As for disc brake.....We discussed it, but we want to keep the car as original as we can. So single master cylinder, and drum brakes are the go! I'm old school. My first car in 1969 was a 66' valiant slant six....I have been driving for a long time, and don't think the car is going to be driven hard at all.
