.I have an 08 Cougar and had the same issues finding something that would fit my dash. I looked at all of the major brands but I didnt have any luck. I ended up going to a custom fabrication shop and showed them some of the existing mounts on the market that I liked and we worked together on creating something that was unique for my console. I know it might sound like more of a headache, but for me, that was the only option if I wanted a dual set up.
Once complete, he was able to powder coat it. I have an HDS 12 and Helix 9 mounted without any issues. Ive attached a few pics as a reference.
