I put this one on my 2011 SR5.

Including unpackaging, it took 5 minutes, and 2 of those minutes included reading the instructions again because I couldn't believe how easy it was (I thought i had to be missing something).
It screws into 6 existing holes in the hood. Could not be simpler, and it looks great.
