Got mine from Livorsi. One thing you will have to do is to make a spacer that fits tightly inside the bezel, and drill 3 holes for the remote, 2 screw holes, 1cable hole. This will keep the remote centered in the bezel. Anything will work such as 1/8" plastic.
3 1/8 bezel 4" OD I'm pretty sure. I can double check mine as the boat is sitting in my garage if you really need to know. I do know the bezel is not the standard size.
