If i turn off and on again it will turn over normally but will hit this flat spot again eventually. This continually gets worse and worse until yesterday when no mater how many attempts i make to turn the starter its always in a flat spot that makes a gravely bad sound. Anyone else have this issue with a bad starter? Is there a modern replacement option for this part? I have replaced the solenoid with a high temp option due to it being right by the exhaust manifold. This has cured the issue of having to bang on it after i stop to get gas on a longer run. It used to get stuck from getting too hot on longer road trips.

The last time i took the starter in they ran it on their test bench and it works just fine. It seems like when it has a load on it that this starts happening.

Any suggestions?

The first thing that I would look for is a badly worn flywheel ring gear. That's what your description sounds like to me.
