Thanks! We've had a number of questions about this since doing it. Believe it or not, these are 01-03 Windstar Sport center caps. They had two versions- grey or black centers. I got mine from my local scrapyard. I see a lot of Windstars being scrapped these days, so you should be able to find some. They actually fit the ST rims very well, as long as you are using the regular lug nuts. If you use locking lug nuts, get the shortest ones you can find, or they will interfere with the center cap...that kind of goes for most caps and locking nuts anyway. We've recently seen an ST in our area that has painted his rims black and blacked out the center of his existing caps- it gives a similar effect, but we do like the caps that we chose. Also, my son had the factory 255-70-16 size tires on it, but we went with 265-75-16 when we did the rims. Here are a couple more pics...
