If a 1970 Mach 1 had the "standard" Sport Wheel Covers as pictured on the black Mach 1, the Marti Report would show no option for the wheels or in other words make no reference to wheels. Cars equipped with the wheels I posted a picture of list "Argent Styled Steel Wheels" in the list of options on the Marti Report. I have had eight 1970 Mach 1s and have had the Marti Report on all of them. Of those, 2 had the Argent Styled Steel Wheels (including the one I currently own). If the OPs Marti shows Argent Styled Steel Wheels, he would have had wheels on the car that are exactly like the ones I posted a picture of. They were a 1 year only wheel and also used on a few Rancheros, Cougars and Torinos. I would be happy to post pictures of the marti reports and other documents if you don't want to take my word for it.
