That must have been quite some force to do that knowing how thick the Advance front covers are! I'm not sure you will be able to push it out as, from the photo, it looks like the metal has stretched, like it does with a power press tool. Shame. Andy's method above maybe the most sensible. Just thinking that something like a fly press might get the worst of it out, enough to grind the indentation out and then finish it off to suit.

Thanks for writing your tribulations up, very useful.
