I just finished writing an article that describes how to disassemble the brake tube tee and pressure differential warning switch that was used on 1970 and 1971 Mopars (B, J, R, and W-bodies) equipped with drum brakes. Here's a link to the article:

I know that a similar-looking part was used in earlier model years. Was this valve used on any other vehicles? Is anybody interested in a seal and spring kit to rebuild valves like this?
