2012 Peterbilt 587 parts?

Hi everyone, im trying to find a website where i can find parts for a 2012 Pete 587. Specifically, im looking for the hood bushings (the inside part of the hood latch)? Not sure if thats what they are called, im relatively new and im trying to find them online but not many parts come up for a 587. Most of the parts that come up are the ones for the 300's. But i was reading on here, and i saw some posts that said the hood and bumpers change from the 300's to the 587. So I would like to know if they do fit or not. If not, where can i find those hood bushings . Do you guys recommend a certain website?

Thanks in advance everyone.
