RAM-MOUNT RAM-B-272U Overview
Ram now has an alternative mounting solution for people concerned about drilling holes in a dash board. This mounting base has a 9 mm (.35 inch) hole that would allow you to install it with an existing bolt on your vehicle. Designed for motorcycles but would work in other applications like semi-trucks. The bolt will need to be long enough to accommodate the thickness of the mount (about 5 mm) and any washers you may be using.
