Brian my intentions are always to be helpful. Never to insult or embarrass you, or give you any reason to be defensive.
The Panteras built after the Vignale coaches ran-out, beginning with chassis #9001, had squared-off rear wheelhouses. The reason for my question is that the first 100 of those Panteras, with coaches built by Maggiora, were the subject of a recall. It occurs to me that some owners may find their car being the subject of a recall a reason for wanting to re-number it.
My reason for wanting a picture of the VIN plate on the foot box, is to determine if its the type that has a window cut-out of it, making the VIN stamped into the chassis visible, or if it is a solid plate with the VIN stamped into the plate itself. My guess is that the VIN plate is the solid type, hiding what lies below. If that's the case, and it were my car, I would remove the plate to see what the number on the chassis below the plate actually is. There's a chance the original number has been brazed-in to eliminate it, and even a possibility a new number has been stamped into the chassis where the original number was, but there's only one way to find out.
