GA you all. I'm planning my cross country trip and thinking abt modifying my helmet for wind noise and my radio. I'm looking for ideas on how to do it or where can I get parts for what I want to do. What I want to do is install a set of cover the ear muff type head phones. What I was thinking is using a sheet metal type locking latch like you would see on an exterior airplane door. I was going to shape a piece of plastic into a cam and attach it to the latch. When I closed the latch the cam would push the muff into the helmet and seal around my ears. I would have to cut a couiple of small slots on the exterior of the helmet for the latches. Where would I find such a latch or something that would work??? I don't like ear buds.
