And upon closer inspection, it looks like your plastic cover and its mounting screws also extend past the bumper perimeter. You may want to also shim the trailer hitch outward slightly, to account for this fact.

I know it's only an inch. For the same reasons that "it's only an inch" is not a valid response to "your robot is too tall", you should address this issue.

Maybe a shim for the lexan.......... but as far as the bolt heads, they can pocket the plywood so that the wood backing of the bumper is flush against the frame.......
