Ultrastik 360s in RA?

I used to use my arcade controller setup with U360s in standalone MAME a few years ago without too much trouble. I’ve always had some trouble with input setup in RA and now I am absolutely hitting the wall trying to get my U360s working in RA. If someone who is familiar with these could do me a big favor and write up a few sentences as a brief dummy’s (me) guide on how to get two of these sticks in an arcade controller working in MAME (current) I would be very grateful. Thanks.
