yeah just the proportioning valve, what kind of fittings do you have on yours, i have two proportioning valves for disc brakes that are balloon fittings if your interested, if you have standard double flare i would suggest getting a adjustable one, i went through joe vanCamp and he couldnt get me one with the standard double flare fittings, so i went with the adjustable one, alot less hassle,

A better option, IMHO, would be to ditch the Factory Proportioning valve completely and plumb in an Aftermarket adjustable unit such as a WilWood. Easy enough to do with a tubing flare kit.
