Hope ya get it Scott. I just spotted one, I haven't seen before either. I took a ride up into, Southern Virginia today, to look at Heavy Duty Dump Trucks, with my brother-in-law. Saw a '47-'50 6400 cab & chassis, sitting beside a barn. Looked pretty decent, but I decided to just buy 400 series, & larger '47-'55 GMC's, from now on. So I talked myself, out of stopping.
