Breezy, what year are you working on there. That looks like the vacuum advance on my '50 216, and that screw with the shoulder is correct. I ran into the same issue (slop from wear). I ended up finding another distributor that had a good screw with little/no wear----after I had ordered a shoulder screw from McMaster-Carr. Don't remember the specs on the screw, but I "think" that it is as Bill described earlier.
