Advice on Rebuilding my 87 300D Turbo Air Conditioning System..

[Carrameow]

My Better Half is very calm and peaceful and says that you dont need AC in the summer, the whole trick is to be tranquil and to think cool. In the summer she does garden work in white clothes and never gets them dirty. However I sweat like a Pig and Dirt follows me like a magnet. Until I mellow, I need AC!
In that respect:
My 87 300D Turbo (newly purchased) has a very weak AC system. I suspect the compressor must be replaced. I have a few questions to those of you with experience on these systems:

(1) Who sells the AC Compressor? Are any of you still using the original model? I suspect that this is the primary leakage area since most compressors last about 15 yrs before the seals go..

(2) Any comments on the High Pressure Hose

(3) Is this a Lost Cause due to the Suspect Evaporator on the 87's?

(4) Have any of you done this also. Here in New Jersey its very very humid and hard to endure without AC

Thanks!!
