Don, Check out how I attached those Oxford saddle bags to my bike. Same attachment point where the reflector used to be just different. They don't allow enough words in a message for me to describe how it all went together. I used 3/8" steel rod, 3/16"x3" plate, 14mm hex socket and a short piece of 1/2" steel pipe. I cut, bent and welded up the frame, aligned it with the seat then welded it all together. poked a hole in the bag for the socket to attach to the 14mm hex head on the sub frame and there you have it. Works great!
