Flyboy,
I removed mine from a 79SC. It was quite a job but straight forward. I would cut the hoses in the engine compartment and pull them out from below. Remove all the clips holding the hoses, the dryer in the right wheel well, the condensers under the front of the car and from the engine deck lid. Then move to the smugglers box and take out the fan and evaporator. It will come out, I promise. Remove the compressor and as many brackets as you can get to. The long one should wait until you pull the engine, something you will do soon, again, I promise.
