First hand experience with changing to the NBS master cylinder WOW! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Found this thread as I was swapping the rear discs on my 97 k1500. Then did the master cylinder, and figured I'd change to the right combination valve. Now I'm stuck, can someone help?

How can I plumb the new combination valve into the abs unit? The diagram shows what I have..the combination valve bolts and directly takes fluid in and the abs unit has three valves out...two valves for the front, one rear. The correct disc/disc combination valve has two ports in three out. The old is two in, two out. I've never liked the abs on this truck..should I discard? What's the proper way to disable the Abs?
