It's slightly awkward because those corners are not 90 degree angles; see photo below. Plus you have to get rid of all the excess double-sided tape and the side window edges are very close to where the mounts would be fitted.
My idea, which won't be better than Pete's, is to glue in a mount on the flat end of the car and provide for a single screw through it to hold the rear of the car's body in place. That means drilling through the metal frame and possibly cutting away a small part of the interior molding but neither is any big deal. On mine I am planning on fitting an illuminated tail sign near that position so some of the body will have to be trimmed away in any event.
