Fold up door latches came out of roof need help!!!

Yes mine does use those plastic latches that you have pictured there and I said the same thing to my wife that they are not very strong to be holding up the heavy door. My camper looks exactly like the one you have pictured. If there is an alternative to the plastic latches that you know of please let me know. We are supposed to be taking this on a camping trip in about a week and a half and I would like to have it fixed by then.
