proportioning valve

[dieseltech]

Hi, I've tried searching this and can't seem to find anything. I have an 86K10 4x4 that I'm swapping a dana 60 from the early 90's. Where my issue lies is with the proportioning valve. the current 10 bolt has 2 lines coming out of the factory valve and going to each caliper on the axle. The 60 that I am swapping in has a single line coming to roughly the middle of the axle and then teeing off from there. All the valves I seem to come across are dual outputs for the front. Has anyone swapped in a dodge 60 keeping the single axle feed and if so what did you do for a proportioning valve.
