I bought one from stylinindustries couple months back. The bolts they came with weren't that amazing and the nuts started rusting right away but I imagine you can just go to any hardware store and get new nuts and bolts for a few bucks. At the moment it's on backorder (?) heres the link:

I ended up taking mine off and moving the plate onto the bottom side of the passenger sun visor so I can flip it down whenever I streetpark. I still have my relocator bracket but I bent it slightly for when I was using it. If you're interested in buying mine, I don't need it anymore and I could try bending it back to its original shape and upload some pics if you want.
