Frustrated. Cannot find a fuel filter for a 1976 308. It's a paper filter that sits inside its removable cannister. Can't even find a part number: Searches at Fram, Wix, AC Delco, Teho, etc. bring up the filter (Wix 33279, e.g.) for the newer 308's, 1980 and beyond, but nothing for the older GTB, GTS and GT4. Could just convert over to the newer filter, but would need the mounting hardware for it and where would I find that?
