Joining the conversation mid-stream.

There was a split windshield on Kijiji in Quebec last week. Do you have one?

The dash panel is a flat piece that bolts to the body in half a dozen places. It isn't very substantial, but I expect it could hold up some extra weight. If the crews were smart enough to put spacers behind the "chicken bar", I expect they would have put a piece of sheet metal to keep the radio from sliding through, or even a fitting for a length of canvas web strapping.
