Picked these up at a garage sale for $20 with some vetter bags:
Plan is to cut off all of the unneeded brackets and build some kind of pannier brackets to keep a couple soft bags off the exhaust. I was going to buy a couple universal loops from TouraTech but they have been out of stock for a while.
I remember seeing a post here where someone built some racks from scratch but I could not find it. I wonder if supporting these from a bracket under the seat and from the passenger pegs will be enough? I might also fab up a tube between the two racks to make them rigid. Might even mount a couple Pelican boxs to them on longer trips if they seem strong enough
