I recently got to the bottom of a similar discrepency involving a '70 Boss 302 Eliminator. Car had the G-code VIN, but the Eminger Invoice and the Marti Report showed it as a non-Eliminator 1970 Cougar - something that was not supposed to exist! The owner had not even noticed the discrepency, as it was definitely a Boss car and was equipped with all the Eliminator goodies when he bought it. Luckily the owner had found 2 build sheets during the restoration, and both confirmed "ELIMIMINATOR" in the remarks.
I presented all the evidence to Kevin and he updated the records to reflect this car being an Eliminator, which also bumped the 1970 Eliminator production numbers from 2,267 to 2,268.
