Call "total performance" in clinton twp. MI.
They have the fms kit for about $35
it removes the a/c and relocates the powersteering up so the car is equipped like it never had it.
when you remove the smog pump, you have to remove the y-pipe off the back side of the heads and plug them(thermactor plugs $5/pr from ford)
if you go to an off-road h-pipe there is no tube to plug there otherwise you need to plug that on the h-pipe.
Then you can remove all the tubing from the a/c (spec. tool $8 from autozone)
You will then have as much room on the pass. side for changing spark plugs as the driver side...really cleans up the bay, alot more access area, and pick up some ponies too.
