Any pictures closed and open and description of how you modded it? Thanks.
These are just iPhone pics - sorry for the poor quality. I mounted it where it wouldn't interfere with air flow to brake ducts or radiator.
On the backside of the plate holder, there are two triangular shaped brace tabs which force the installer to mount the bracket about 3/8" proud of flush or they will strike the spoiler when the plate is open and the plate won't sit completely upright.
I hated the look with the bracket sticking out from the spoiler that far, so I just took a hacksaw and a file and removed those two triangular brace tabs. Then I was able to mount the bracket flush with the spoiler and the plate sits upright and against the spoiler when open.
I'm sure removing those triangular brace tabs reduced the strength of the axle where the plate rotates on the brace. They are there to withstand the torque generated on the plate when open and in the wind. Since I plan to run my plate retracted virtually 100% of the time, I really wasn't too concerned about removing those tabs.
If you plan on running the plate open all the time, then consider the strength reduction involved when removing those brace tabs. I have enclosed an image showing the tabs I removed.
