Disc Conv. Proportioning Valve - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok gents... I have just installed rear disc conversion on a 8 lug FF 14bolt on my 1971 C-20 burban from scratch using custom cut brackets, cadillac rear calipers w/e-brakes and front rotors from a 1971 4x4 K-20. My question is ... do I run my newly added rear adjustable proportioning valve before or after the stock disc/drum valve unit and if I run it before, do I have to block off the input and output of the old valve?

Any thoughts would be great.
