I have a set of 15” Appliance wheels that I bought new in the 80s for my 1973 Ford Thunderbird. They are 5 on 5” they don’t fit regular ford cars but those years they fit big Lincoln’s Tbirds Cadillacs olds …. I was told it was 5 hole Chevy pick up bolt pattern but the center is too small to fit on a pickup. They aren’t perfect ,a couple have rust but aren’t too bad overall. I do have adapters to fit on 5 on 4 1/2 ford cars that’s what I had on my 56 ford before I bought new wheels. The tires are Marshals that look like new but are 25 years old . $200. Ask for Wayne
