Does anyone know what the ' AC ' stamp on this same wheel represents ? Thanks, Brian
Brian, all of the original Ford wheels have a 2 letter stamp on the backside at center hub. My assumption is that this stamp was what the assembly line workers used to quickly identify the size of a wheel, IE: Diameter, Width, and Backspacing. Your 'AC' stamp should identify a wheel by it's specific dimensions. I have seen AB, AC, AD, BA, BB stamps, among others throughout the 60's.
I should note that this applies specifically to Motor Wheel Corp. manufactured wheels. Kelsey Hayes might have had different identifying marks, other than these numbers.
