[V6-12v] 1994 90S A/C Compressor R&R experience

[Tom Christiansen]

Folks,

My A/C compressor has seized. I do intend to replace it... I have a rough 
idea of which parts need to be changed (drier/receiver, some little screen 
that I forget the name of, the compressor, some o-rings).

The question is: How much work is involved with changing the compressor?

I've been looking at it from the top... Looks like it's more or less 
impossible to get at the parts from the top. A bottom up job... Looks like 
the oil filter may be in the way. Will this compressor job require that the 
oil filter be removed or that the oil cooler be removed? What are the 
common snags of the procedure?
