Like Rich said, get yourself come .090 brass, and make one. The hard part is done, you have the hole pattern, just make one a bit smaller than what you have. Or, tweak the one you have. You might be able to file a gentle curve along the bottom and reduce the width of the tail to get you out of the woods. Either way, you need to do this before you inlet obviously. I see your bench has the dreaded ETK2M(every tool know to man) disease. I hate when that happens, and it happens often to me.
