Default 1970 formula ac brackets

I'm confused on what ac brackets are correct for a 1970 formula 400 ram.air 3 auto. I bought a complete set and helping a friend find some for his car and I seen different parts pop up. As a teenager I built runners from rollers and gathered 70-73 brackets . I had some friends take my original engine out when I was 17 because 1 blew a head gasketand buy in a bone yard engine. Can some please share any isometric drawings or pictures of ac pump. The 1st picture below are my restored brackets I.bought and what's confusing me is that I have aluminum bigger brackets saved in my parts crate. I found simular brackets on ebay and was wondering if they are installed as well or are there 2 different types. Of ac systems. Please teach me.

All the Aluminum brackets are for 69 and or early 70 usage which does NOT include Firebird. Your first pic in your First post above looks correct.

Sourcing original bits & pieces/building a set.

-Cast side compressor mtg bracket is '70-73.
-Stamped steel compressor front SUPPORT is '70-71.
-There are a BUNCH of different stamped steel A6 compressor front supports. Over the years have pulled A6 compressors out of the trunks of quite a few Pontiacs I hauled in & the stamped compressor support wasn't even Pontiac. Unbolted, that stamped piece went into a stack til later when was able to ID them as big block Buick, Cadillac, etc.
-In the past year went through through & sorted a huge plastic tub of original Pontiac AC bracketry pieces. Bolts, spacers... aargh. Most came from retrieving buckets, boxes, & cardboard trays from a local's estate. Amazing what using a roll of masking tape & an ink pen will do to tag loose bolts.

I thinking of saving my parts car for future project and if I do I'll need extra brackets since it's missing some. Maybe you can help me make a complete set. Thanks for the story of experience.
