A full box of ten individual, new old stock, Champion #UF-14Y spark plugs.  The box has some shelf wear, but the individual plugs are unused, as shown.  The box says engineered especially for "Ford Falcon Mustang Thunderbird, Mercury Comet Lincoln Continental"  Note - the listing is for one box, but we do have two boxes available as shown in the last couple pics.  We are not an automotive supply so we don't have access to the books etc that show what fits...but our research shows they should have the following application (please verify with your own sources, no refund or return).
