I'm installing sport mirrors on my 68, I found a perfect fitting mirror and gasket combo (from 75/76 nova and omega) the gaskets are in good condition but I'd like to get new ones if they are available. The part number on the gasket is 1701311. GM Parts direct didn't list them. Any ideas where I could track these down? I haven't been down to the local chevy dealer yet, probably will get there by the end of the week.
