As long as you are willing to play around with the mounting brackets just about anything from the 70's to early 80's will work. The Vetter bags all mounted to the hardware the same its the way the hardware mounted to the bike that changes. Many people put this stuff on these bikes so there is hardware out there but takes some searching.
I'm not sure if you've done some searching on ebay or not but you can try names like bates, calafia, and off course motorcycle saddlebags.
If you lived near my location I have a set of Vetter bags in rough shape & the mounting brackets have to be adapted to better fit my bike. I took them off previous owner had bastardized a system together with the mounting hardware.
Just keep looking, you'll find something. Also check craiglist. I myself have gone to a large pair of throwovers that work well & look good on the bike.
