SBP drums to SBP disc parts list

Hello everyone. I am trying to determine what else I would need if I bought these parts from this thread: http://www.forabodiesonly.com/mopar/showthread.php?t=249438

I have a 70 dart Swinger with complete drum brakes all around (9in up front, 10in rear)

I already have SBP so I won't need the upper arms.

Things I will need:

New calipers (will any other "make" work or do I have to search for actual replacements?)

Soft Brake lines (do I search for make and model with disc for these?)

Master Cylinder? (Currently have drum all around)

Proportioning valve? (do I search for make and model with disc for this)

Ball joints, and control arm bushings, and shocks since I'm going to be in there anyway.

Is there anything that I'm missing?

Thanks in advance!!
