Do all Supers have upper and lower molding's?

[weim55]

I'm looking at a 71 Cheyenne Super that seems to be a very original unmolested truck. All the interior appointments check out but I've never seen a Super with no lower molding's. I looked up inside the lower bedsides, no original trim holes. Truck is all red with what looks like just one repaint, no sign of two-tone anywhere. The SPID is damaged and worn to the point it's almost completely unreadable. I can make out YE in one of the code boxes but nothing else. Are there any other codes that start with YE? Solid color Supers do exist, yes?

Thanks,
