I'm in Mobile, AL. Where can I get good deal on the correct part set for the tire jack on an '03 LT? Just purchased a beaut with only 121K miles from a local big business dealer. Saw that it was missing during my hard look-over before negotiating the "as-is" buy. Don't want to go too long without one in the car. (This is my second Tahoe - first '95 made it to 313963 miles !) Thanks !!
