GIVI MONOKEY PLATE ON AN 1150GSA

Has anyone fitted a Givi Monokey top box to the rear rack of an 1150GS Adventure? I can see there's an aluminium Givi monokey plate for an 1150GS but not an 1150GSA. There's a universal Givi monokey plate but it's for tubular rear racks so I can't see it fitting.

Answered my own question by buying a Givi E251 Universal Monokey plate. With the help of some drilled metal plates from B&Q I managed to fix it securely to the GSA rear rack for my Givi Trekker Outback topbox. Sportsbikeshop are doing some good deals on Givi right now - the Trekker Outback 42Ltr top box is only £225 delivered and the E251 plate £40.
