youll need the bracket kit that moves the powersteering pump up, its a VERy easy job, and shouldnt take you more then an hour if you havent done it before, you can do it with basic tools.
The hardest part removing it from my '88 was getting the condensor out. I didn't have the spring lock tool at the time, and was in a hurry, so I used a hacksaw to cut lines until I was able to get everything out.
The A/C eliminator bracket came with zero directions, and I didn't have access to stangnet at the time, so I spent about 6 hours trying to figure out how to do it.
I regretted it every minute I owned the car after that. I felt zero increase in power.. and the absolute worst part was, it was summer in Arizona. Nuff said.
I think the best part about removing it was how it cleaned up the engine compartment. If you have the A/C spring lock coupling tool, you can easily disconnect the lines from the evaporator core, then just unscrew the fittings from the compressor, remove the condensor, remove the lines, remove the compressor, unbolt the power steering pump, move it up to where the compressor used to be, get a little bit shorter belt (don't remember the length exactly,) and call it a day. Then next time your heater core takes a dump (and it will,) remove the evap core all together, and plug the holes in the HVAC box where the lines exit.
