1964 1965 Cuda *HUBCAP* buyer's guide?

When looking for 64-66 wheelcovers, the centers are just held in by bent over tabs. If you find 1966 14's you can swap out the center with a 64 or 65 center from a 13" wheel cover. 14's are pretty hard to find, the ONLY difference between a 13 and a 14 is the clips that hold them on the wheel.
