Yes, they will interchange.

That said, I had an old salt dealer tech tell me that there was a slight difference in an early 616/617 and a late 616/617 starter such that they would bolt in place but were different such that one combination, early on late or late on early would put it in a slight bind.

I have never confirmed this to be true, but I thought I would pass it along.
