Air Conditioning Question

[special.k1@domain.elided (Kevin J De Vries)]

     I was wondering if anybody cold help me with a little problem.  I am
currently stripping my '78 Scout that was rear ended last summer and 
I am parting it out(HINT: I'VE GOT PARTS FOR SALE).  I am now going 
to disconnect the air compressor, but I don't want to lose any of the 
freon so I can save the Ozone layer and reuse it for latter(MAYBE).  
Here's my question:  I was scanning my service manual and it stated 
that if you open a valve on the compressor you could transfer the freon 
to the compressor and close it off leaving the rest of the system empty 
to freon.  I'll do some more reading, but would greatly appreciate any 
and all info on doing this or any other way of safely removing the freon 
from the system.  Thanks in advance.
