72 C20 factory air conditioning restoration

[540ChevyC20]

Hi All,

Looking to re-fit the factory a/c to my 1972 C20 BB after completing an engine swap. I'd like to keep the setup looking as factory as possible, going with modern parts where it makes sense. The new engine won't allow me to use the original compressor setup due to it having much taller valve covers, so I was thinking of instead using something like this:

I think I'd want to plumb this in to the existing air box and evaporator - here's a couple of pics of what I removed from the truck. I believe a previous owner has already changed the setup from factory as all photos of seen of the stock setup look different.





I don't know much about a/c but am keen to learn. If anyone is able to help me figure out how to make this work I'd really appreciate it!
