Denny,

So does that mean that the dealer also changed the VIN number. Otherwise how would you authenticate that this was not something the person did themselves much later? That it was a true W code.

Denny,

I'm not suggesting anyone is wrong. I'm just curious about whether any were ever factory installed. I have a lot of information on muistangs including the original 1968 information and many books since and they all mention it as you have said but there are no production numbers.

Thanks for all the info.

Rob
