Tank bag Parts / Fixing.

Hi, I acquired A GS Tank bag when I bought my 04 1200GS, It's in very good condition But I feel its missing a part, IE the lower rear fixing. Although it has a velcro pad that adheres to the tank, And a fixing that Zips on to it from the bag But travels no farther, IE on to the Base. I fear there is a part missing that connects to the base of the tank as there is a metal part screwed to the Base, What I'm asking is the Tank bag in fact complete? or do I have a problem? I'm asking mainly as I don't need the Bag and want to sell it if anybody interested,

You might be able to see what's missing at http://www.realoem.com/bmw/enUS/showparts?id=0317-USA-06-2004-K25-BMW-R_1200_GS_04_0307,0317_&diagId=77_0047

Thanks, Woland, it looks like there is nothing missing just the Metal sticking Velcro pad! Pad that iv unstuck from the Tank, and still have, which can be replaced, For $16.00, About £10.00 or just reaplyed with some M3/M5 Tape. Cheers Mate.
