OK, I took some more photos. Like I said, I'm having trouble matching up what I have to the diagrams above. Maybe I'm just not seeing it correctly, or I suppose the PO could have messed with it even more than I originally thought (entirely possible).
So here's where I'm at - first, on the AC diagram -
I see brackets 20 and 14 (I think), but I don't see 16 or 21 on the front. I do see that I am missing some of the rear left stuff that should attach to the large bracket that I originally posted about (3). Would that be 7? And 10 is for trucks without AC only?
On the Power Steering pump diagram -
I see bracket number 6 and 12, but not 13. 13 I think is the same as 7 in the other diagram.
Thanks!
