NONE of you guys have seen a '64-'67 Cyclone with these before? I'm kinda surprised. They're FoMoCo-spec originals, used those years on Mercury Cyclones. Ford of Australia used them on their XR GT's during the late '60s. I have a set on my shelf I planned to use on my '65 Comet, it took a while to get them on eBay as I was always being outbid by some guy from Australia on 3 or 4 previous sets I bid on. Sets tend to run $200 or so for usable sets (you'll note fronts and rears are different) without much damage. If you plan to use them note where the valve stem is in relation to the lugs, not all wheels will work. Some offsets (amount of dish) won't work either. Original '65/'66 Mustang wheels will work, and they're not too tough to come by.
