I couldn't say for certain, but I doubt they'll fit - the Mk. 2 iteration of the 990 (from 2007 onwards I believe, and including the SDR) had a larger capacity fuel tank. I may be wrong and am happy to be called as such by more knowledgeable members. In the absence of a more convincing answer, why not get the vendor of the side panels to send you photos from the side and above so you can remove one of your panels and compare? In the meantime someone may come along to give you a definitive answer...
