Resurrecting this thread, as I'm having the same issue myself now...Linky no worky above - seems like this should be a fairly "generic" and/or GM part - can anyone give me a P/N for the correct part that I can just go to my local auto parts store and order? The Isuzu part number would be my "fallback", since I'd prefer to just buy it locally and get it the next day. Guess I'll buy the tool off Amazon too...
