Help me identify the A/C system in our 1979 Scottsdale

[Alpha C10]

I have searched the internet with no hits on this. We just bought this 1979 Scottsdale and it has what looks like an older aftermarket A/C system in it. Can anyone identify this and tell me the brand or any info you have on it? See the pictures.

Not sure what to do with it. Doing research on it for now. Probably will pull it out. Thanks for any info!!

That might be quite an investigation in your near future. Maybe someone has some old copies of the JC Whitney catalog to check

In that era adding AC was quite common. There was a shop near ours that specialized in AC conversions. ARA is one that comes to mind. Appears they are still in business.
