I am searching for the black plastic clips that hold the forward piece of headliner trim up against the windshield. Does anyone know where I can locate these? They always break when pulling that forward piece of trim out, but I can't find anyone that sells them aftermarket. I tried Original Parts Group, but they said no. However they do have them for the El Camino, but I don't know if they will work or not and they don't have a clue either.
