I'm upgrading a jon boat for small lake fishing. I am looking for a source for aluminum forms which bolt to the inside of the jon boat. These forms provide a flat surface to mount the control box or a stick steering assembly. I have seen them in other modified jon boats but cannot find a company that sells them. Anybody familiar with these products?

Ever thought of just making what you need?

Go to HD or lowes and get you some sheet metal bend it to the shape you need to mount your stick steer on and attached it to your jon.
