Welcome to the Quilting Board!
Marge, I sure can't figure out how to answer a PM. I really appreciate your contacting me.
The 301A is a slant needle. I think slant needles came out about the time I bought mine. I have a universal ruffler, and it doesn't fit. I think I should ask the company if there is a part number. I would hate to have you send it if isn't going to work on this machine. I looked at them both side by side, and it's really hard to see why the universal won't fit and won't work, but it won't.

No marks in that area on my black 301. When I opened the door, I was surprised at how clean it is in there!
