Grocery list for a/c please

Summer's coming up and I just remembered that my car didn't come with an a/c and last summer sucked not having one lol So basically I need a list of all the things i'll be needing to install one. Thanks guys

compressor, belt, bracket,drier, tubes, and the interior switches. The the holes should be in teh block though so you should be good there.

oh yea and the thing in front of the rad

How difficult is putting an a/c on a car that didnt come with one in the first place?

good question, everything will be easy except for the wireing. i totaly forgot about that. I am not sure what wires are not there. There is a plug for the compressor and i thin goes to the interior switch but i am not completeyl sure.
