Typical American marketing, advertising a product for sale they haven't actually made yet, seen it time and again. Often disapeers without trace after a couple of years. I do like the recall wheels, they are so of thier time.
I've been after a set of these for years, when they were reproduced by speciality wheels I didn't get a set as they worked out over £2600K once back in England & I didn't have the money back then. I thought I'd wait they'd always have them, big mistake !. The repo ones weren't 100% same as originals center cap was flat (like 1 in your pic) and something to do with trim ring.
Over the years the ones that came up on EBay always had something wrong with them or we're missing bits. If you do find a set everything has to be there trim rings center caps & lug nuts as your never get any if they are missing. These wheels are easier to find in Mexico, when they got recalled that's where they all got sent.
Originals were 15 X 6, repos also done a 15 X7 & there were a couple of different types I've seen.
A couple of weeks ago I spoke to everyone I knew in the US if they knew of any sets going the answer was no, bloke that was selling he's 69 500 with them on wouldn't sell them.
