Grab rail fitment to RGS or Goldstar with Blade type mudguards.

[richardrocket]

Hello Twin people! I want to fit a grab rail to my Super Rocket which has Goldstar type mudguards and brackets. Although I can see that the front of the grab-rail attaches to the top of the "hockey stick" mudguard bracket where the mudguard bridge attaches, I would like to know where the rear tabs of the rail attach. Any one got a bike with one fitted? Any chance of a photo or a sketch. Just bolting it to the mudguard with no additional support seems a bit flimsy??
