Yamaha 1300 Tourer - Yamaha 1300 Tourer Fansite

Folks. I am very interested in the 4" sissy bar extensions that I read about on various posts here (and I have even seen a picture of them on someone's member site), that seem to be made specifically for our OEM Tourer Sissy Bar. Can someone please steer me to a website/store where I can obtain said extensions?

Also. I purchased the K. Ultra Tour sissy bar bag (awesome), but it is about 6 inches longer than my luggage rack and seems to want to fall off the back even when empty. Has anyone else run into this situation? How did you resolve it? I am considering a plexiglass plate that would attach to the luggage rack and then serve as a base for the entire bottom of the bag...but there has to be something I am missing here. Most of our luggage racks are about 9 inches long and the bag is 15 inches deep. How did all you folks that recommended the bag attach it to your "short" luggage racks? Thanks...
