Ok....I guess I should have looked at your pic. Upside down won't work for you. Take the bracket off, use some snips to cut that bracket and throw the piece with the sticker on it in your bag. Pull if out if you ever need to....and if you get pulled over, I am sure you were on your way to the HD dealer to buy the appropriate bracket to mount the thing.......
When I had my Softail I cut the plate off cause I was proud of that 200mm rear tire. Trimmed it up and drilled a hole in it and put it under my passenger left side foot peg. Never had an issue and got pulled over once for no helmet and the cop was cool about it. Thought about doing something like that on my new SG but havent got around to seeing if that would work.
In the spirit of following the law (that made someone on here laugh on another post), mine is mounted on the rear exhaust hangar on a L-shaped bracket.
Here is where i had my side plate mounted on my 98 at front swingarm, shipping day 4-7-11, had to put quiet exhaust on it to be able to get it into Norway, where the buyer lives.
