These reproduction firewall plugs are identical to what GM used on 1970-72 vehicles 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.
