Since nobody responded; probably not any experience with this case. Anyway, I will finish this off in case another has this question.
I removed the tail piece and removed the plastic cover on the underside. Next I drilled the pre-marked holes on the Wing tail piece. Remarkably two of the holes did mate up with holes on the Emgo bracket so i installed bolts accordingly. Next I drilled holes through the existing two on the tailpiece and thru the plastic on the Emgo bracket. Installed two more bolts and tightened it all down and it works fine!!!
Here is a picture of it mounted on the scooter:
NOTE: for those not familiar with this case it is lockable and removable, so it can be used like a small suitcase and removed and taken into a hotel or whatever.
Hope this may help others!
