I apparently ran over something with my 2002 Trailblazer (4WD, LT if it matters) because I have a metal L shaped bracket that got pulled back and ripped when it got caught on whatever I ran over. theres an idental, mirror image part on the drivers side. the bottom part of the "L" rests under the radiator (far end possibly supporting some of its weight?), and the top part is held with one nut to the frame behind the bumper or grill. I cant for the life of me find out what this part is called. Not even in my Haynes manual. I even called dealership parts stores and the best they can tell me is to bring it in to look at it. It looks like a simple replacement. Anyone have any idea what this part is called, and if so, a OEM part #?
