Does anyone know where a person can get the rubber boot type seal that the hatch hinge sits in? Nissan isn't sure if it comes with the hinge and not certain they can even get the hinge. MSA and VB don't show the part in their catalogs, that I can find. I've checked online, nothing. This was the only reason my '75 had any rust, water came in there and eventually rusted through the sheet metal below, then the floors, etc., etc.! What is everyone doing about this seal? I don't want to let it rust again! I haven't found any good used ones, either. Thanks.
