BTB, guess what????? I got my alloy engine mount from Hobbythek about 10 minutes ago !!!! AND, it is 1mm Larger than the stock one. I guess I'm in the same boat as you !!! LOL. Well here we go, let the mods begin, gotta love it. I just ordered mine last week, I guess they might be WRONG about the other mounts being correct like they responded.
