73-74 AMX & Javelin rear rectangular tail light gasket kit made of heavy foam seals you press into the tail light and back up light lenses, on all 73 and 74 AMX & Javelin. You can use a variety of adhesives on back to affix them. Replace your brittle, cracked or missing ones with this set of four. 

The tail light section on 73-74 AMX & Javelin is extremely prone to rust and I recommend POR-15 in this section for your restoration.
