Seen a couple of threads about the scarcity of Givi wingrack fitting kits for a RD 04 but was wondering if anyone had tried modifying a RD 07 fitting kit?

I recently acquired a set of Givi Monokey boxes and am desperate to get 'em on my bike!

Any suggestions as to how I can go about doing this would be greatly appreciated, either by modding the RD 07 fitting kit (which I have) or acquiring the proper RD 04 kit.

Thanks in advance!
