(Remove the AC system)
I know that this may not be totally necessary, but it sure is helpful. I've only seen one person that was able to keep their AC and do this mod with the stock manifold.
You will be removing the AC compressor, lines, and condensor. This is necessary because you must move the alternator over to the space that the compressor is occupying to make room for IC tubing. Here is a in progress pic to show what I am talking about
This is very easy to do and I will not go into every step. You must evacuate the refridgerant first, (or accidentally like I did).
. Radiator needs to be removed to get at the condensor in front of it. You will save about 10-15lbs by removing all of these items. Compressor is proabably 10lbs, so if you don't remove the condensor, no big deal, it hardly weighs anything.
Note how much room is left with no condensor or radiator. This would be perfect for a V-mount (which I highly recommend).
