I got out as much oil as I could by dumping it out of the compressor, then added oil and 134. I changed the dryer and most of the O-rings also.

I don't know of any differences between the compressors.

Since you have the system "open" you should replace as many O rings as you can and the dryer. You can get a new dryer from autozone for ~$50.
