After a quick search, it seems like my Delphi is a GM HT6, so PAG 150 it is.

Any comments on all the links I just found during my search which brand the HT6 compressors as "known belly-leakers"? I was trying to keep everything OEM in an attempt to keep the replacement process as simple as possible, but now I am wondering if that O-ring is going to crap out early or if there is something that needs close attention to detail during the installation process to avoid this. (My bad if this should be a new thread.)
