I was looking through Ray’s short fiction bibliography on Wikipedia and found it lists none at all after 1965. I find it unlikely that he suddenly stopped at this time and it also says that the list is incomplete and can be expanded. I seem to remember Driving Blind and One More For the Road having new stories but perhaps they were rewritten old ones?

Yes, he did.
