So yesterday after a car wash and after driving all the way back home, I find out my lund windjammer came off somewhere then after searching most of last night and all of this morning, I find out lund discontinued most of they're products. I've had that thing on so long, I can't imagine my truck without one. anyone know the GM part number for the rear air deflector / spoiler? or did they discontinue those too, because they discontinued our trucks...
