Love the "New old stock" Motorcraft or OEM stuff that's still floating around out there for older vehicles like my 89 Motorhome with Ford 460 engine. Much better quality than so many of the cheapo aftermarket parts being made today. I use the cheapo aftermarket parts when I have to and, in most cases they do well enough but I feel much more confident about a repair when I can use a part like this new old stock Motorcraft rotor button.
