Combination Valve Install question

I just bought a set from Rick Ehrenburg's Ebay store. They work perfectly, and are affordable. If you don't know Mr. Eherenburg, google him. A great Mopar resource. I'm not plugging him, I don't work for him, but his parts have helped solve a bunch of problems I've had on my '70 Swinger 340 brakes. If I've broken any rules, Mods, I apologize.
