Removing A/C compressor on 1993 Z34

[v8powerplant]

Any tips on the easiest way to remove the a/c compressor on a 93 Z34? Was driving it right after charging the a/c with a new can of R134 and the next day it was blowing so cold....wonderful. runaround Then it went warm....and there's a scraping noise coming from the compressor. I'm thinking the clutch on the a/c went. It's making a similar noise as a brake drum when the shoes are worn.

Guess it probably not easy to remove that clutch mechanism so should probably replace the compressor as a unit. But need to get it off the car first.

Thanks,
