proportioning valve
I have a 71 250 switched the front axle to a 79 dana 44 with disk breaks and am looking for a proportioning valve who has the best one that will fit the best bought 79 brake lines and put a booster on the truck.

The PPV SECTION of the COMBINATION VALVE is vehicle specificat calibrated. If you don't have the correct valve from the vehicle you salvaged the brake system from, you maybe should consider using an ADJUSTABLE PPV.
These valves are usually rebuildable with available kits. If you want to keep the METERING VALVE and PRESSURE DIFFERENTIAL VALVE on the truck, the PPV section can be removed (internally) from the COMBINATION VALVE and an ADJ PPV plumbed in behind it.
Was the truck DRUM/DRUM before the FRONT DISC changeover? You will need a DISC/DRUM MC, preferably the one from the donor vehicle.
