Many pop rivets can be removed and replaced with a new one. Use a drill with the appropriate size bit to drill the center of the pop rivet. You need to find a way to grip the pop rivet with vise grips so it doesn't spin and drill slowly so as not to melt the plastic clip. Rivets and backer washers are made in various lengths and diameters. They are available from walmart and hardware stores.
I keep a set at home and one in the camper.
