Yep as @Tripps said R3T fitment but you could get one to fit a Roadster without too much effort.
Its all doable if you want to play around and experiment as I I tend to do.
If you wanted a dual headlight dipped screen a cut down and refinished used Triumph one would do the job.
I only test fitted mine before I wrote the Bling Dream off.
Looks a LOT smaller with the extended Thunderbird Storm risers I had fitted!
Easiest would be to use the accessory Std/ Classic/ Roadster screen fork clamps and add bobbins to fit a QD screen or use the bobbin mounts as well if spacing / ease requires.
The Thunderbird ones I have would probably do, as I use their QD screens to fit R3Ts with just a lower bobbin change to a smaller 17mm diameter pair that I get from the Thunderbird screen mounts.
