1965 Valiant disc brake upgrade

Update:
I have few questions still unanswered, but I am working on these. The majority of my questions were answered by 57dodged100, the Kelsey-Hayes Disk Brake Swap Thread. He did an excellent job including a parts list with vendors… super helpful.

Originally, I didn’t go for the drum to 76’ single piston caliper because of cost and the size of the job. I was trying to avoid the cost of replacing the 5x4” x13” wheels and the rear end swap to 5X4.5 lug pattern. As it turns out I still need to buy new wheels because the 72’ calipers will not fit into the 13” wheels. So I may only save a bit. There may be a less expensive way to change the rear bolt pattern than an axle swap, but I haven’t found it. I already purchased the parts from a 72’Dart and I am happy with the choice, so I am going to keep moving forward. Also, I am doing all of the work on a borrowed driveway. Each day I work on it, I must make the car drivable afterward… or at least pushable. One part of the project at a time, doing the work mostly by myself so I’ve got to get everything lined up first before I take it apart and the surprises begin to occur.

Unanswered Questions:
I am not sure which proportioning value to use to replace my distribution block. I plan on taking pics of what I have and doing a comparison. If this looks good will use one similar to stock, from a 1972 Dart with front disc and rear drum.

Using an adjustable type seems like it is more work than it is worth. I don’t really want to plumb if I can help it.

I am not sure about the plumbing from the master cylinder to the propositioning valve. Hopefully I can use that from a 72’ Dart. Its a going to be a daily driver, no drag racing.

The same goes for the Master Cylinder. I maybe going to go with the 10-1326 clip on top version recommended by Rocky_JS. It is the same as the “Fabled” BENDIX CASTING 2225541, except less money. This is for a power or manual system, 67-70 A-Body. I have not pushed the button on the purchase yet.
