source for rivets for the rear hatch gasket/weather strip?
 

Some time ago my car was involved in a rear ender and the body shop removed the gasket from the rear hatch. Somehow the broke off or lost the rivets that held it in and used whatever plastic retainers/rivets they had in the shop. Does anyone know a source to get proper ones? The ones that are there now do not do a good job at all.

Thanks
