I haven't got any pictures, but I had exactly this problem. I assume you're talking about the later style TD5 dash with the centre console with switches round the outside and the radio in the middle. The radio used to fall out when I went over bumps. I bought new components but couldn't get them to hold together, so I gave up and fastened the fascia panel to the centre console with self tapping screws. I spaced them evenly so it looks like they're meant to be there (there are other visible self tappers on the standard defender dash of that era anyway) and my radio hasn't fallen out since.
