Well Spanky my math comes up different. 100% of the COE's I've owned were five-window cabs--both of them. I think this time I'll trust your experience over my math.
I knew the 450/470 fenders were wider and would have assumed that extended to the steps also, but I didn't realize the steps were taller. Are the fenders taller also? I'm now imagining a number of sheet metal pieces are different below the level of the cab.
