I am now able to provide a rack extension that bolts to your Givi SR346 rack. As it is 16-1/2" wide, this should make it much more versatile. Below is the CAD prototype design I came up with. It easily attaches using four longer screws that I provide. They will be powdercoated wheel silver like your rack but other colors are available. Cost is $180 plus S&H. Actual photos will be posted when available. If you buy one, you will need to notch the black plastic Monokey base with a Dremel so it will clear the lateral tubes - an easy job. PM me if you want to pursue.
