Bought myself a ball mount so I can hang my GPS or my phone. Mounting the ball underneath seemed like the best choice so I can still use the top of the dashboard for other things. (Mail from the mailbox)

Take the window and the dash cover off
Line up the mount and drill from the back side
4 x 10-32 x 3/4 stainless panhead screws with a nylock nut
Since it's a single layer of plastic I made a backing plate out of sturdy sheet metal to spread the load. Put a little bit of a curve in it to match the plastic.

Suggest you order that part and have it available for replacement.
The backing will help, I assume you saw how flimsy it was after your install and went back to strengthen it. That plastic will crack over time...

Run strap / plumbers tape from your mount bolts to that black metal support bracket. Should firm up any movement

Did that when I made a dash top mount for the big bike. There was too much flex in the dashboard and everything was wobbling around. For that I ended up making a custom plate 6 inches wide and 12 inches long that could reach the only hard points available.

Will see how this works once the ice melts and I get a chance to try it out.
