Replaced my bonnet badge today, and am pleased with the result. It wasn't straight forward though, as most things Morgan aren't. The curve of the badge was greater than the original/bonnet. That was cured by placing the retaining screws between the gap between my decking planks and pressing it as flat as I could get it. Leaving a slight spring, which went when the nuts were tightened. The bolts could have been a little longer, to make putting the nuts on a bit easier, but the result below looks much better.
