I have 2 625's, a 625-3 (1989) and a 625-8, and a supply of .048 moon clips I aquired in the 1990's. .048's work in the 625-8 but not in the 625-3. I am currently clamping the .048 moon clips to a piece of angle iron and grinding off about .005 and finishing on a belt sander. This seemed to have fixed my 625-3 clip problem.
