At the link in pretty much a standard system although you don't need the proportion valve unless you have issues with the rear of the truck coming around during hard braking, however the valve also works as a safety valve incase you lose line pressure to one of the wheels, which the valve will close off the line to both rear wheels or one or both front wheels and requires a special tool when bleeding the brakes. Helitool recommended a GMC 3/4 ton front calipers, outside piston diam. of 2.935 inch. The master cylinder for the truck uses a 1.250 inch bore. Is the truck plumbed with 3/16 or 1/4 brake lines? Hopefully this might help.
