Red arrows = drilled holes to find plastic framework.
Yellow & green circles = Eonon front mounting screw holes.
Green stars = Carpet covered timber battens hot glued to factory framework.
Framework has been cut with butane powered hot knife. Not pretty, but necessary.
I think I also had to file some metal from the front edge of the brackets, so they sat deep enough into the enclosure and made sure the Eonon faceplate was flush with the dash.

Good luck!
