Single to dual master cylinder on 64 Dart - What do I need??

sure, the Dual 67 drum/drum MC and a wilwood/MP proportioning valve (like 30 bucks)/ Run front reservoir to original dist block through the P valve, and block the other ports. Run the rear reservoir to the fronts through a T. Thats all. 2 new lines for front brakes. Crank the P valve until you can lock up the fronts just before the rears.
