MC and Proportioning valve advise

[Peanut74]

Ok, now that the windshield is installed I working on the brakes. I am at the point to where I need to order a power master cylinder and an adjustable proportioning valve. I have read all the threads that I found on the site but they did not match my setup.

What I have:
-'67 cab/ pedals
-'71 frame/ All brake lines (3/16"OD front line, 1/4"OD rear line)
-'71 front disc brakes
-'71 power brake pedal rod
-Rear disc brakes (Single piston calipers)

What power master cylinder and adjustable proportioning would you recommend? Would like to stay with a OEM MC if possible.

Finally found a thread that had some useful information:

Looks like I should get a 77-82 Corvette MC or early GM, Autozone P/N NM1521. I will research them tomorrow and see how the fit up. As for the proportioning valve I think I will look at the adjustable Willwood valves. Will probably call them to help me sort out the one I need.

Also in the same boat! It’s a bit of a nightmare to find. I just want something I can bolt to my booster with proportioning valve and will mate to my inline tube kit!

Surprising there’s few definitive threads on it.

The disc drum CPP master , mates up to the stainless inline tube brake line kit .
