Installed some BMW pannier racks. Good thing I am not paid to do so.
EDIT: Today 5/18 I revived some used aluminum panniers from a 2009 GS to mount. They were not too bad with only a few scrapes here and there. They had a lot tree branch scratches and the like. I used 0000 steel wool and metal polish. Worked great and they look ready to go 5 more years.
