2000 Fleetwood Southwind exterior cabinet latches

Where were you when I was learning the hard way?? Ok, what's done is done and I will no longer slam the doors :). Going forward though, I removed the handle mechanism and removed the corner frame screws and the bottom piece of frame. The sides won't come off because I can't remove the screws from the latch areas. The screws just spin. I assume that means the holes are stripped or is there a nut or some other piece that's just spinning inside?
