Here is a parts list with numbers..

I am starting this project now. The part arrived today. However it did not come with any bolts to mount it to the frame. I will be heading back to the dealer tomorrow to get the bolts. I have a 2018 Chevy 3500hd, dually, long bed, 4wd. The part number I got from my dealer is 84164444. As stated before, this does NOT include the new heat shield (which I also for got to get) the mounting bolts or the caps to cover the holes in the bed. I ended up getting mine from gmpartsnow.com. This is a Chevy dealer in Grand Rapids, MI. I found that the biggest difference in price is the shipping charge so shop around.
