My GTi's AC compressor is leaking and we have tried to tighten the bolts but it did not help. It looks like Ill need to buy a new AC compressor. Its a 2.0L.

I am hoping you guys can help me get the right part for the lowest price possible. The URL below shows two of them but I don't know what the different aside from manufacturer is. Please elaborate, or provide a link to the exact one that Ill need. Thanks.
