Good question....so far as I know, there are only two places you can find the build date on these trucks...first and best place is the build sheet & the other place you can check is the blue label on the door latch side of the driver's door, about half way up the door. Otherwise, you can get close if you can locate any date stamps on things like the transmission, engine, rearend or even the carburetor. Hope that helps.
