Bed looks to have the original maroon paint, but we have a turqoise hood, so maybe cowl panels and fenders got changed out sometime in its life, compare vin on registration to vin on frame side... right and left side just below door or top left on frame just behind the engine mount...
Lol. I checked the vin like you said and your right vin is for 65 but its the same vin on the pink slip and it says 64
Look on either side just below the door on the side of the frame rail. you might have to use sandpaper to reveal it...!
Found it on frame rail. Same as cab so its a 65 maybe first sold in 64 ? Oh well ill see what comes up when i register tomorrow
