typically the evaporator is left in place during an ac delete due to the difficulty in removing it. however, it is relatively simple to remove everything else.
here are the replacement parts you will probably need:
-all a/c lines that have been removed
-mounting hardware for lines, condensor, compressor, accumulator
I would make sure to flush out the evaporator at least 3 times, especially if the openings were left unplugged.
