2021 Pete 567 bunk restraint parts question.

I contacted JGP, my dealership, with my vin and because it is a single bunk, they can not find the parts I want.
Attached are a couple pictures that show the metal seat belt like buckle in the corner of the bunk and the plastic clasp buckle hanging from the ceiling. I found several pictures of 579 double bunks with these same features.
I wish to get the metal seat belt pieces that go into the corner buckles and the male plastic pieces that hook into the buckles in the ceiling.
Where and/or what can do to find these?

 

Awesome. I will ask for a price on a new one, or maybe even call about a used one in good shape.But those are the parts I want.
My rig is single bunk, I dont need double, but I take my guitar with me from time to time and want a place to put it out of the way. So I think I can use the hardware and make a simple "hammock" of sorts out of plastic and fabric, that uses the already existing buckles etc, in the sleeper.
