I may have found at least 1 quarter panel about 5 hours away to pick up for my 66. I could fix the rust it has but I am very anal and will always know the repair is there.
I know there's one at National Moparts in their yard and even has the rear window. Haven't seen it up close but maybe a goldmine. Not that much further distance
Their phone number is 705-426-2993 and ask for Nigel
I can phone for you if you want and get details.
