I’m looking for a replacement combination valve for my 1990 k1500 as mine was leaking out of the front metering valve.
I thought this would be something easy to find, but I am having a heck of a time finding one that matches the original. My original valve has a metering valve on the front and a proportioning valve on the rear. I actually bought one from a parts truck as it looked the same from the front and got home only to find it did not have the proportioning valve part in the rear (just solid aluminum). I’ve since looked at several other trucks in salvage yards and none of them have the proportioning valve in the rear. What gives? What year/options do I need to be looking for to have the proportioning valve?
