Atwood screen door latch replacement

[Monaco slide out travel lock]

I have a 2004 windsor and one of the slide out travel locks plastic trim covers has came off and some of the other covers have broken rivet. Has anyone else had this problem and if so what is the fix? It looks like the rivets are plastic and go all the way through the wall of the slide. The screws that hold the travel lock assembly on are rusting so I am replacing them with stainless steel.

Thank you for your help.                                                                                             Jim
