350 to 455 Air Conditioning

So I’m doing a 455 swap into a 71 GS 350 with factory AC. What do I need to make it all work on the 455? Any help is appreciated.

 

Never done the swap, but probably just brackets.

 

I use my 1970 350 brackets on my 455. Fit fine.
Aluminum base and the metal top.
On the power steering I used the 1973 bracket the pump was on from donor engine.
I think the aluminum 350 bracket might work but at time did not try.
Using the 73 455 pulleys if I remember correctly as I also have a 71 core engine but is preserved in oil sludge.
Many parts interchange I found.
My 70 is an early car 11/69 build if it means anything.
