The plan is to have my GPS on a Ram Mount with the wires going into the left glove box through a grommet on the side. Inside the glove box there will be the power connection and a Audio connection. This is so I can disconnect the cables and take the GPS off when not in use.

The question is for someone that has taken the glove box out.
What is the distance from inside the glove box to the inner left panel under the Handlebar?
I need this to buy a grommet and they are all different heights.

Thanks in Advance.
