Have you seen this DIY for the mounting hardware?
DIY: Steps to add rear tonneau mounts for those without
I don't think you're going to find anyone selling the cover with the hardware on this forum. My understanding is some (or all?) 2009 models did not come with the hardware installed from the factory. 2010+ come with hardware. So if anyone with the hardware pulls it out, they are left with a big hole where each piece goes.
