Changed the oil on my buddies 2011 Chevy a half hour ago, I noticed one of the "grooves" where one of the mounting bolts go for the air box lid is cracked, and the bolt is gone, torx head bolt. I'm assuming the lid for any 1999-2013 4.8 5.3 or 6.0 Vortec would work. Does anyone have one for sale or know where one can be bought along with the correct bolt besides the dealer?
