Three 66 Ply. hub caps, and Four Plymouth caps 13"

Are these 13 or 14" covers? These are correct for 64-66 Plymouth Valiant and Barracuda models. The first ones with the "Plymouth" logo are 1966, the others with the Valiant logo are 64-65....only the plastic emblem is different and can be changed. Never used on Dodge models but do look great on them.
