I cut down adhesive back velcro to fit the crevice. I use hot glue sticks ,holds mint

I have not used it yet, but Miami has the hard hook. It sure looks like a lot of the factory versions. You can use the standard sticky back and it will work just fine. I actually prefer to mount it sideways rather than flat, but it will work either way. Just soak the foam with landau adhesive first before you stick on the Velcro. That will provide a slightly firmer sub straight for the Velcro to stick to, with less chance of the foam just tearing out.

Nice idea! Thanks for sharing

That is a neat idea. Thanks Andy
