Where can I get one of these???
those are usually broken when you do find then and brittle as heck when you find a good one. I'm not sure, but I think it can be flipped over to use on the other side. if so the you can take the good one you have to a machinist and have them mill one out of high strength nylon block (I'd make 2 or more since you can't be the only one needing them.) or you could get someone to cast them for you.
