I noticed both of the rubber gaskets (they look like washers with gaskets on them) that go over the AC line sleeves are gone. They're the ones that fit between the hard AC lines and the AC pump itself. I stripped that bolt hole out, thinking the line was just loose- it turns out that I was missing a rubber thingy. I pulled the other one off and it ripped in my hand from the coldness. Looking for a part number or at least a proper GM name for it so I can get my AC back together and charge it up! thanks

 

go the gm parts they ought to have what you need, and even pics for you to look at to point out what you need.
