Welcome
There is a repair kit available, I think it is from Devon 4x4, not sure if you need to take the screen out but I don't think so? I seem to remember it is a bracket that screws down with self tappers along the leading edge.
Personally I'd fit a new dash, its not as expensive as you'd think and it makes an interesting project which takes less than a day to do, I did my own one on my old Discovery and it took 4.5 hours having never done it before.
