Here is one fix I have done. Friend had a similar problem, built-in that went out, wanted to use something bigger and the Ram mount was the only option. We went down to the local hobby store and bought some 1/4″ model aircraft plywood. This is _not_ the same stuff you get at Lowes, etc. It is a bunch of layers of wood glued together, without voids, etc. So solid stuff. We cut one piece of this to _exactly_ fit the hole he wanted to fill. We cut another piece about 1/2″ larger all the way around. We then glued the two pieces together using polyester resin (which you can also get at the hobby store in the model airplane (the kind that actually fly) section. We now had a “plug” that would cover the hole and since the back piece fit the hole exactly, the cover could not slip around, which is what had happened to his first attempt at a fix. Next, depending on what is in your shop, take a router or sander and round/bevel the edges to give it a more professional look. Now take that same resin and paint the wood. And sand it. And paint it again. Do this 3-4 times and it will end up looking like a perfectly moulded piece of plastic made to fit that hole. Now you can paint it whatever color you want, and even put a logo decal on it if you want. Or if you have a couple of gauges or something you want to install, you can drill thru this plug and mount them in it. You can then use screws and angle brackets on the rear, so that you set the plug in the hole from the front, and then use the screws from the rear to let the angle bracket catch behind the dash and hold the thing in solidly. Be sure to re-resin any holes you drill to keep the water out. It is not as hard as it sounds, and will look like it is made into the dash when you finish.2008 Pantera Classic2014 Mercury Pro XS 200
