Discovered something interesting on the 1/18 scale ACME Ramp Trucks

On the Ford Ramp Trucks the letters FORD on some of the trucks are located higher on the hood than others, you see the line in the hood on the below photos, on my Black non themed ramp truck the letters are below the line on the front of the hood, the same thing with my Shelby Ramp truck the letters are below the line on the hood, but on the COBRA themed dark blue ramp trucks the letters FORD are above the line on the front of the hood.
