Does the Bolt come with the small mounting plate for mounting it directly to the stem itself? The full size Elemnt comes with one.

I don't know if this would work for your specific case but I got one of these from ebay from some random seller in China for like $4. Link is not the same seller, just an example. You have a lot of options for where the bar is and the position of the whole thing itself (up high, down low, out front etc..)

The bar part is NOT 31.8 like the clamp end, it is smaller but most flashlight mounts can go on smaller bars, keep that in mind.

I also got a few generic Twofish lockblock style mounts for about $1/piece. The combination works pretty good.
