Missing part??? (pics attached)

[fishman]

This started as an occasional squeak when I turned the a/c on. The belt looks great so I figured I'd check the tensioner. What a horrible design! Anyway, I think mine is frozen and needs replaced. So I decide to remove the tensioner and "work on it" a bit. That's when I checked the handy belt routing guide under the hood, and I swear I'm missing a pulley or something. Can anyone tell from the pics if I am missing a pulley under the alternator?
Thanks for the assist!

Well it's not really missing, that is a general design placard you just do not have that other component. It is an option thing if I remember right air/vac pump or something like that. Personally I have never worked on one that had that other component whatever it is.

The only thing that is missing, is the second alternator that your truck is NOT equipped with. THIS is the correct diagram for your truck:
