This reproduction firewall plug is identical to what GM used on 1969-72 Grand Prixs equipped with either TH400 or manual transmissions when no kickdown was used. Over the course of time, the original plastic plug is often missing. We recommend replacing it in order to keep warm air and debris out of your passenger compartment.
