I have a 1971 Camaro and I have two floor pan drain holes that call for a 2 inch round plug instead of the customary oblong shaped plug (holes behind the two front seats). None of the Camaro parts houses seems to have the correct plug although some floor pans were stamped for this plug. I think it may have been a rubber plug but I am not sure. Does anyone have any suggestions?????

 

Cut a couple of round pieces of sheet metal and bond them in place, (panel caulk). Spray the under side with undercoat.
