My 65 Galaxie came without a fuel tank and I have not yet found a supplier for a new tank. Will a 66 fuel tank work instead.
Im sure youd be able to find someone parting out a 65 Gal. Did you check ebay? If you cant find a tank there, message someone selling parts from a 65 and ask.
65 is 20 gallons and 66 is 24 or 25 gallons so the mounting straps from a 66 will be needed and will bolt in.
