what year is my pickup?

That may possibly be a manufacturer's tag for the bed. There were a couple of different mfg. making beds in those years, especially the longer ones.

I believe the FF would be the box model #, 7 1/2 is the length of the box, followed by the serial # of the box.

that is the part tag for the box, has nothing to do with IDing your truck, it's a 7 1/2 foot pick box, not sure what the FF means, but there were a few different styles of boxes on these trucks, yours is most likely a factory installed box though


OOPS I see now after I posted this has been answered.
