the compressor, all the lines, the evaporative canister thing, the radiator like thing that goes over the radiator, the fan that goes over that, r134 refrigerant, the cooling system in that car originally was r12 but u cant get it nemore cuz its too expensive and have to pay a certified tech to do it for u, ur looking at an upwards of 600-1000 dollars of work if ur not doing it urself so it is a pretty tough task, if uve got all the parts from a parts car or junk yard in good condition ur looking at maybe 200-300 dollars.
