Copied from the ad, I've highlighted, and underlined my concerns
This is an authentic Gran Sport in every detail; 401cuid nailhead small block, drive train upgrades, ect - except for the steering wheel (walnut racing) and the air cleaner (chrome). All matching numbers, every option but a few. This auto is in excellent running order and has always been kept in such; 3 month old valve job and new bands in the 300 PowerGlide tranny. Every piece of original trim is in place, save 3 items.
