Dual point Distributor bushings

I have it all if needed PM me You sure the advance plate is worn? Be the first one I have seen in 40+ years of doing this. Might just need cleaning and re greasing.
I took apart another distributor and tried that part that has the points lobes. The part that slides over the top of the shaft. It is loose too. The shaft where that slides on is smaller than it should be. Someone "Rebuilt" it. I'm not sure what they did. So basically, I need a whole new distributor shaft.
