reinstalling ac in 86 gn, how hard?

[Tfreestyle]

This is my first GN so im still not 100% on the cars yet... I got the car without ac. I have been debating on reinstalling the ac, how hard would that be? exactly what parts would I need and approximately how much would it cost? is there any other solution for those hots days except opening the windows? like some type of portable ac unit I can throw in the backseat and take out on race days.

those drives on the hot days to meet ups or just cruising really suck in 100+ temps. Any help would be appreciated

your going to need a/c lines, condensor, a/c housing from cutlass or regal, heater core, and some other parts i cant remember, if this is my old gn your going to need a new a/c compressor also.
