I know that the compatibility of the two has been talked about several times on here. But my question is a little different. I bought both used, in a bulk purchase of accessories off another bike. Neither came with the actual mounting hardware. So I'm aware that they share some mounting points. When doing both, which hardware do you really use for mounting? I'm assuming the GIVI hardware, and just shorten the spacers? I'm getting ready to order the GIVI parts kit for $40, which I'm assuming doesn't include shipping, as trying to source some of the pieces locally; especially the spacers and metric all-thread. Is turning out to be problematic.
