Well these arn't from the junkyard. My dad put airbags on his 2000 silverado 1500 and took these off. All I had to do was knock out the studs and make the holes just a hair bigger, the jeeps hole to hole is just a little bigger. I havent measured to see where they need to be exactley but I figure i can use washers to space them down or cut the rubber if they are to long.
