Shoeless, welcome. With the difficulties which have been mentioned with the high mounting, I'm wondering if an under-screen positioning might still be possible. Depending on the position of the screen when lowered, there would be plenty of room for an M2 on a short base and tilted slightly upward. If it wasn't desirable to have it positioned there permanently, it could be placed into position when the screen was lowered.
