vintagemotif,
Thanks now I feel a bit easier about doing this. I have a 99K that was rusted up badly and when I took the feed dogs out to de-rust them the screw shrunk. Not kidding, it was holding but now it's too small. I've yet to figure this out. At first I thought I was confusing the feed dog screw with another one. But I can't find any other screw like that, and I'm not missing any.
So I was a bit paranoid.
I've got 8 of these babies to do.
