you could go to a hardware store, and look around for screws/nuts/bolts that look similar to that, and modify it with epoxy putty.....you know like skulpt out the details over it?
just a thought!

no broblem hope things work out for you!
I personally don't know any people who sell costume parts, since I always scratch build mine, but if you don't like to do that kind of stuff, modifying only screw or a bolt should still only take a few minutes.
