Part number is 10388091
Its like $10 on gmpartsdirect.com.
I dont have install directions on the computer though, only printed out.
Took me about an hour to install. They def. do not bounce at all anymore, but i need to readjust one of the headlights because its aimed a little higher than the other one.
The kit basically has a metal arm that replaces the white pull tab. the arm goes in the same slot as the pull tab and goes over and you attach it to the radiator support frame right behind the headlight. Then theres another small tab that you screw into the plastic bracket behind the headlight. You screw the other end of that tab into the metal behind the plastic bracket. Before doing this the plastic bracket wiggled pretty easily, now it doesn't.
