power to manual brake swap

I have an 87 ram d100 I put a 440 in. I want to convert to manual brakes because my brake booster hits the valve cover. I'm not sure what master cylinder to get, and if I need a different proportioning valve. I know I need an adapter plate for the firewall, and I can make the brake pushrod work. Just wondering what parts will fit/ what to look for. I know its not an a body, but any help is appreciated.
