Sissy Bar Bag for 1700 LT

I looking to get a sissy bar bag for my 1700 LT as it would be handy for stuff like a lock and chain etc. Triumph list a large sissy bar bag for the Storm (Part No A9520080) but there's nothing listed specifically for the LT.

I thought I might be able to sort this out myself by checking the sissy bar and rack part numbers for the Storm to see if they were the same as for the LT. But no - though the items look exactly the same they have different part numbers. Arrgghhh!

Does anyone have the large sissy bar bag and will it fit an LT sissy bar and luggage rack?

 

And the answer is that the large sissy bar bag will fit the LT so I've ordered one. When it arrives I'll post a pic or two so you can see how it fits.
