I am also needing one of these. Those 3 p/ns do not show in any search I have done as remotely available today. Is that the same as Delco 172-1353? There are aftermarket valves available on Ebay and Jegs, but the price varies widely. The interchange appears to be most trucks and big cars like 70s and 80s. Are any of the aftermarket ones any good? Mine (on '83 K20) has the light on, I have pushed and pulled the pin but it does not move. I have a new Delco master cylinder to put on at the same time, but I don't really want to open up the system until I have all the parts to fix it on hand.
