I have a 62 super sport for sale and twice buyers have backed out because they say the vin is wrong for an SS. A man in an impala club confirmed that it was correct but I don't know how he did it, so don't know what to tell buyers. I know it is an early car & was sold with an automatic on the column which I guess was only available for a short time. Vin is 1 21867 B1484 50 Any help would be greatly appreciated.
