63 Dart/brake line

[JimD]

I'm going to install a dual master cyl. on my Dart. I want to use conifer lines, what size are the brake lines, and would 6' be enough, thanks in advance Jim.

Conifer or Monel 90-10 Copper-Nickel Brake Line Tubing?
why?
to replace all 3/16 lines in a-body will need about 6 6ft lengths. A lot of older connections break or strip. The real issue is the fittings to the master cylinder.
