Presumably they are attached to the alloy skin and you need a backing? That could take the form of a block of shaped wood which I guess is how they were done, or a shaped piece of steel with some threaded inserts riveted inside the skin, you have probably thought of both these which is why I am intrigued by the problem, is it more complicated than I am imagining?
