The window sweeps (also called dew wipes or felts) go horizontally across the top of the doors and touch the inside and outside of the glass, they keep the windows from rattling and 'wipe' the glass as it is rolled up and down. This set is contains 4 pieces to cover both doors on the inside and outside, without chrome on outer sweep, made just for your 1977-1979 Pontiac Bonneville 2-door Hard Top.
