Know this is an old thread but, just saw it. If you want the Kodiak badges, the part #15651236 (GM Part)
You can use a hair dryer to peel the C4500,etc. badges off. The Kodiak badge has two pins that can be broke off and Cat Power on the the bottom. You can either leave that on or do what I did and cut it off with a cutting tool. It looks good. No dought what truck I have so I'm not asked anymore. Hope this helps.
