72 big block a/c bracket question

[jocko]

Can a big block expert take a peek at the a/c brackets on this ochre truck for me? They do not look like the original brackets to me, however, am wondering if these are the correct brackets for a CA truck with a smog pump perhaps? (the ochre truck is a Fremont truck, but has always been registered in NV its whole life). For comparison, I posted a pic of sameyrasmea's awesome original big block - his a/c brackets are what I remember on prior trucks as exactly correct, but the ones on the ochre truck seem a little odd/different to me. (sameyrasmea, hope you don't mind if I posted your engine pic - it's quite a useful reference for me)

The main question is the orange bracket on the ochre truck that is over the forward passenger side intake manifold bolts - looks kinda like something is missing or maybe not... Does the smog pump mount that high on these things? Looks like some sort of pump/device could be mounted in there.

Would LOVE to see a big block pic with a smog pump for comparison. Thanks for the help.
