I do have a question about the steel wheels. I went over to my father's place to look at the steel wheels on a couple of C-bodies that he has, and the 15-inch wheels did not look right. When compared to a 14-inch the 15s had much larger slots (holes) in them. I am including a drawing to show you what I am talking about. Is this normal for the larger 15-inch wheels or am I looking at the wrong versions?
