'47-'53 Identification Question

[Chevyboy1962]

Hi Guys,
I was wondering, how would I identify wich year of the '47-'53 Chevy trucks(split windshields) has the 1 piece door windows?

Earlier today my Dad & I spotted a potetial next project partially disassembled 3 window rotting away in a well overgrown (bushes) driveway in the old part of town. I only noticed it, because it looked like it was coming right at the passenger door. lol

The things I see missing off hand from the street (assuming they have these parts) is the grille, bumper, radiator,fan, drivers door. It still has the original dark green paint with wide rusty chrome reverse mags all the way around. It still has the 235 inline 6 still under the hood. It is a short wheel base stepside to boot!!

I know there is certain years, doors, and other small items that only fit certain years of this body style, what are these?
TIA,
David
