Need help finding a Front Hubcap..

I have an 2012 T660 and recently I had a 4-wheeler run into the side of me and crush the hubcap. So i've been looking for a replacement and can't find it. Every Hubcap seems to have 5 or 6 little holes and the one on my truck only two. I've called two Kenworth dealerships and even stopped at one and they say they don't have a clue what kind of hubcap that is. So with that being said, do i need to get an Hubcap kit?? I was about to pick up an Hubcap kit but supposedly I had to have the exact lugnut size?? And that i didn't know so i just left it..

The Kenworth guy was really non-helpful at the dealership, basically it seems like i was disturbing him.

 

Cool, I'll stop at the dealer later and see if I can find it

 

One more question, is removing and installing the new kit hard to do yourself??
