5KT: anyone replaced their A/C compressor?

["Arun Rao" <rao@quattro>]

	After I had the system recharged last week, the air conditioning
	on my '85 5KT worked OK for a couple of days before the compressor
	gave up the ghost (it's probably the clutch: makes a horrible
	grinding sound).

	Now ... has anyone out there replaced their A/C compressor?  I
	can get a rebuilt one for ~$150 or so (this is an AC Delco
	Harrison compressor) from the local chain store, but a look
	at the instructions filled me with dread. Among other things,
	they tell you to replace the drier, use some special kind of
	grease to coat the O-rings with, etc. etc. -- failing any of
	which will void the warranty!

	Is this really something I cannot/should not attempt?  I thought
	it was a simple matter of having the freon recovered, replacing
	the compressor and having the system recharged: in fact, the
	Bentley says nothing more than "flush the compressor with nitrogen
	or R-11 (?) before installation".  (Not that I would be able
	to do that, either).

	TIA.

	-Arun
