spinner center caps

I have a 67 Barracuda and I have switched over to the large bolt pattern front and back. I have some mustang bullitt wheels and have the clearance problems on the front with the dust cap that many have already experienced. I have been looking for a good looking cap I can make work. On eBay I found spinner caps that are designed specifically for these wheels. It appears that they have the same form of mounting and a deeper recess for the spinner part that may clear the dust cap. Has anyone used this for their fix for center caps?
Did you find anything more out about these? Or have a link?
