2015 T-680 Help! Cannot find part name or number

I have a 2015 T-680, that recently failed inspection for several things. I have been able to locate all parts except one. There is a rod that runs horizontally underneath the sleeper in the rear with bushings on either side. The truck failed inspection because the bushings are worn out.

I have had no luck dealing with Kenworth in getting the part. They cannot seem to find what I am talking about in their system. No schematic or diagram. I'm lost on how to find it.. no amount of google searches has turned up anything, and i'm trying to get the parts before the weekend. Does anyone know what that part may be called? or any advice on where to look?

The inspection shop called it a "body cross arm"

I appreciate any help!
