Can somebody help me with these hubcaps. Part Number # 1674212, 15 Inch dia. with Flipper center. The hubcaps have a 55-56 Windsor back with the spinner bolted on with three screws. The outside dia.of the flipper wings is 9 3/4" and the dia. of the center cap is 5 1/4 ". There are plastic incerts that fit in the center of the flipper cap. Two have Windsor insignias and two have New Yorker insignias. They are held in with a single cross bar spring clip. The man I bought them from said he thought Chrysler came out with these caps to be dealer installed to add a little more flash to the cars because they were not selling well. I have never seen these either inperson or any pictures of these hub caps. There similar to the 56 Dodge spinners but the spinners are larger. Can anybody help?.--- Gary Barker
