I've been told that I need a 14x5 for a 63 Bel Air 4-dr with a 283 V8, but I'm confused as some have told me that the rim is 5-1/4 and others have said 4-1/4. Could someone please clarify this for me and tell me what the 5-1/4 and 4-1/4 refer to? Also, what year range did the Bel Air or other full-size Chevy's use this size rim? Regards, Mike
