well I guess I kind of found out thru some of these knowledgable board members. I asked a lot of questions when I got my truck.The over cab running lights were dealer adds because I was told there should be a recessed impression in the top of cab, mine wasnt.The unity spotlight wasnt offered,Some dealer did a good installation though.The dual air horns with the vacuum pump wasnt factory. It could have been installed by anyone, but the install was done cleanly like a dealer or a anal mechanic would.It has a rear sliding window that definately looks fact. but isnt on the protecto plate.front bumper guards , not on the protecto plate.Aux. gas tank was on the protecto plate ,but my third tank was a add on by dealer or ?. I was told on this site that the cruise control in 72 had two different installations. One was operated by the turn signal lever, Mine is an under dash button that says master cruise.
It has a transmission cooler that isnt on the protecto plate.
