I have been looking on-line at 1960 Bonneville Convertibles. Most seem to have vinyl bucket seats or vinyl bench seats. I assume these are replacements. The 1960 catalog states that the Bonneville convertible comes standard with leather seating. Can I assume that vinyl was not available and that both standard bench seats and the optional buckets are leather. So the restored cars with vinyl would be incorrectly done. Thanks
