Here is a 1111498 Distributor that has been professionally rebuilt. Date Code is 8 L 25. The shaft etc has some pitting and the 498 is kinda tough to read-but it is legible.I don't think the pitting /corrosion will have any effect on it's function-and I was assured that it wouldn't by the rebuilder.(he builds motors for a living/hobby etc.)The distributor is a tough one to find.I had it done for a project that I am no longer going to do.$150 shipped to your door.It is correct for 396/350H.P. cars
