Got my skidplates delivered Saturday and swung by O'Reillys on my way home from work today and picked up 8 bolts.
Got home, pulled it up on ramps, grabbed my cordless drill, 15mm socket, creeper, and removed one of the factory bolts from the bottom of the front splash shield. Used it along with my drill to make quick work of tapping the 8 holes. Installed the skidplates using the cordless drill/driver also.
Easy peasy, except that the snow we got here over the weekend is kinda melting and the bottom of the vehicle was wet and dripping on me.... Lol
