Reinstall of AC...am I missing anything?
 

I have a 1971 Chevelle with a 1981 350 small block from a pickup in it. Before I got the car 20 years ago the AC had been removed. I'm finally able to work on the car and recently picked up what I'm told is a complete AC system for a 71. The guy had removed it all (working at the time) from his car to put in a Vintage Air system. My plan is to install the AC as I slowly replace most of the front clip of my car. I just don't know if I'm missing any pieces. The factory box is still installed on the firewall (don't mind all the rust...keeps falling out of the way gone hood), I see I have the condenser, compressor, and what I believe to be the drier, along with a bunch of tubes & hoses. Does it look like I'm missing anything? I'm hoping once I get the front clip back in shape I'm able to just take it somewhere to get it charged.

There a plastic diverter on the floor vent. I would advise getting the r-134 retrofit switch with high and low pressure switches. Keeps the compressor from working if something is wrong. Burning up compressors. You can still run r-12 but this kit just lets you have pressure switches. Which they didn't have in those years.

The original should still be in the car as it looks like only the quick and easy things were removed. I may have to look into that upgraded diverter though, I think I've seen those on a few sites.
