Thanks Barry! I guess the print is so small in my code book that came from GG that I couldn't see it
I've been through that thing numerous times!

I know of a 77 CrewCab that the original owners son says is a factory in cab that I dismissed as dealer installed. being the truck has been on the farm since new & now finding this out I'm more leaning towards believing him

As far as the ClubCab & other truck I'd have to say those are dealer installs
