HI, It took me 3 hours on blogs and the net trying to find these for my truck. These fit perfect for the rad cover plastic part and to go to the Chev dealer is like $1.25 each so this is way cheaper and you get alot more. I wanted people to know that they fit so they don't have to waste all of the time that I did looking for them. Again yes they fit a 2010 Chev Silverado 1500 under the hood plastic Rad cover. I hope this helps:)
