10/15/19: I got around to addressing the distributor advance slop. I previously found the pin connection was worn so I fabricated a shoulder bolt on my lathe and it tightened it nicely. When I pulled the distributor, I also noticed that the gear was turning slightly on the shaft. I ground out the pin, and found a suitable roll pin to take it’s place. It is now tight to the shaft. After reinstalling the distributor, resetting the points and timing the engine, the timing mark is still bouncing around about 3 degrees.
