Ok, this is what I have come up with. I still have to clean up the rough edges and paint it but will hold off until I decide what color to do the interior with. I think UP may actually have this interior on their site.
The part is made of copper clad epoxy circuit board with brass tubing and brass threaded spacers.
Fitted to the car. Note the scotch tape over the adhesive. The frame now drops out after the screws are removed.
How it appears from the rear.
And from the side.
The length of the thread spacer was determined by seat back height. If I had to to this over I might carve enough of the seat back so this adapter could sit below the window. It will get painted to match the seat so likely not noticable as the car whizzes by.
