Want to borrow to replicate: 6th Gen OEM luggage mounting hardware and backrest

The title is pretty self explanatory. I just bought a top trunk for my 6th gen but it doesn't have the passenger backrest and is missing the hardware that mounts the mounting base to the rear carrier. If somone isn't using their top trunk at the moment, I would like to borrow the hardware simply to replicate it.

I'm also missing the passenger pad as it seems to be optional on whether or not to install it. Mine was apparently never installed but didn't come with it either. I'd like to buy this personally but if I could borrow one from somebody that would be great as well. I want to either replicate it or take it with me to a local shop that sells Givi stuff and see if I can match it to something similar that will work.
