Thank you for helping clear that oddity up. I may never know the specifics surrounding the swap but at least it puts that scenario to rest.

Do you have any insight for the AM Radio and the Rally Wheels? Since both are considered "options" they should be listed on the invoice but they are not. Would they have been installed at the Dealership? I can understand how easy it would be to swap Wheels but the Radio has me baffled. Why would anyone want a mundane AM Radio added to the vehicle when it was new? Keep in mind that it looked Factory installed when we dis-assembled the Dash.
