So.... redoing the fuel system on my '69 Charger. The square, metal "ring" or "plate" that covers the rubber filler seal, in the trunk, is rusted and all but useless. Does anyone have a part number or at least the proper item description so I can search? So far, all my searches bring up the filler neck and that rubber seal but NO mention of the plate that holds the seal down. All help would be appreciated. Thanks in advance!
