The rear loop
I'm using it as a rack. My plan was to use it to get firewood while camping, and it worked really well for that. It came in the box of parts but I don't think it came off this bike. I knew it might look a little funny...
Clay......we'd need a closer look but I'm pretty sure it's goes with the bike......but maybe we'd need another thread? Unit Single rear fender loop? Posted to the BSA board? I think it's the rear fender's that's either not stock or has been modified?
60's ( Asian) rear racks can be adapted pretty easily.
You got a couple of flat bars maybe 3" (ish) with a hole in each end in your spares?
