4 wheel disc brake plumbing

ok i need to plumb the brake system today. below is my crude drawing of my plan.



4 wheel DISC brakes

cobra master cylinder

manual brake conversion with correct pedal

all original rear brakes and lines

I do have a proportioning valve from wilwood, but unsure if needed, or where to place

Stick the prop valve in the rear lines. It's used to cut down the pressure going to them so the car doesn't lock up the rears and try to swap ends on you.



What kind of car if it?

thanks!!!!
