1968-1972 Removable Rear Window Weatherstrip Screws. This set of four attaches the weatherstrip to the body. The rear window on 1968-1972 Corvette T-Top Coupe was removable for more air flow. It had a weatherstrip around the perimeter mounted on the body. When the window was in place, it sealed very well. If you have air or water leaks this should seal and solve any normal problem.
