GM Factory AC

[chufham]

I have part of my factory ac left some was missingwhen I bought my car.I have found the factory ac brackets and old compressor in a local junkyard,If I buy them and use the compressor for a core and buy a new condenser I guess thats what it's called in front of the radiator what else would I have to buy other than new lines to have ac?.I'm sorry this is long winded.
