I have my beater 49, know where there is a 51 or newer about 20 miles away. Have seen a couple year unknown (just saw the beds or tailgates) right era within a few miles. A couple 48-50s in the immediate vicinity (next person wanting to buy mine for parts gets shot).
Back in Washington I could put my hands on 5 48-50 1/2 ton panels on my routes.
That green and cream SS clone... swap the green over to dark blue, paint the wheels dark blue, and make it a 3 window cab and you have where mine is heading. But, my bumpers and guards and such aren't getting chromed (hate that stuff).
