@LeevonI admire your commitment and work, awesome job, iam going to do some of your fixes to my truck, just one question man, are these the new nuts that gm is supposedly using they're black washers with silver nuts and have teeth ("teeth" because i dont know the correct term) on the outer edge, or should i re-use the silver flat no teeth slightly larger in diameter ones that are what came with truck ? Wish i had a pic of the original nuts. I got the new ones from my dealer, but i just don't trust them. They messed up the tsb pretty bad, they just squirted in sealant didn't remove the spoiler nothing, kinda glad they didn't, they would have messed it up even worse. i hope they gave me the correct nuts, just want to make sure.
