Distributro repair idea

[redmodelt]

After a while the center flange where the upper plate rides get worn around the center allowing the upper plate to move back and forth which changes the gap in the points. We also have a number that show cracks in the thin part. What if the distributor was put in a centering holder and that area was machined out and a sleeve pressed in to bring back to size. Has it been done? The distributor body being cast iron, would a steel sleeve work?
