I have a set of 15x6.5" rallys and wanted to throw them on the cuda so I could get those awesome cragers off of the car. These from what I understand are dated 75-77. I also noticed that they only have 3 mounting holes for the center cap. I wonder what vehicles these came on? Ramcharger? Road Runner? I have some center caps that I am sure would fit if I drilles 2 more holes, but if I cannot get trim rings, up for sale they go and I will buy some 15x8's for the back and use some new 15x7's I already have for the front.
