This listing is for an original used accessory wire grommet plug [double opening] used on 1964 - 1965 Pontiac A body cars including GTO, Lemans and Tempest models. This grommet protects wiring passing through the firewall and locates in a 1 and 1/8 inch hole in the firewall near the fuse block.
This grommet was removed over 40 years ago from a wrecked 1965 Lemans convertible and on that car, one of the 2 pass through openings in the grommet was used for the convertible top power supply wire pass through. Grommet has been stored indoors and is still pliable.
