It looks like I have some very similar on my 629-6. But they seem to fit a hair off, but not quite as bad as what you have. I didn’t have an issue with the fit because they were cheap if I remember correctly. I might consider sending those back, or sending that picture to them and see what they say. Even if one “only” spends $20, they should fit a lot better than that.
But if this picture works we have about the same stocks, so maybe they didn’t turn up the “Continuity” button on when one set was sent through the machine. (Poor punctuation or something. Sorry.)
