Need A/C compressor

I am installing power stearing on my 95 Geo and can't find a tension pully for a non A/C car. So my next step is to put an A/C compressor on just to use as a idler pully.
Does any one have a old A/C compressor with a good pully and bearing.
Also, I know that I can use one from a 95 to 2000 but are the older ones the same?

Thanks for the help
