Wilwood "Drag" REAR Drum to Disc conversion kit

Sorry to steal your post. I wanted to go wilwood discs all around on my 69 swinger and wanted to know which master cylinder and which proportioning valve to use. On summit they dont offer a power set-up. I would call wilwood and quit being lazy, but being deployed in afghanistan makes it difficult, and I would like the parts waiting for me. Another question, is it worth it to make it power brakes? I intend to make it a cruiser and is currently in full resto-mode, sitting on blocks after full media blast/primer/undercoat.
