You will need a Macpherson style strut compressor. If you ask for a spring compressor, you might get the wrong kind. Auto Zone loans them out for free with a $40 deposit.
I had a heck of a time getting the arms for the compressor inbetween the coils when they were compressed in the strut assy. After doing my own strut assy, I would recommend having a shop do it. (I wont do the strut assy myself again) But everything else is really easy.
