I second the call on the Vector... take a look at this auction:
http://www.ebay.com/itm/VECTOR-14x7-...95c6dd&vxp=mtr
While its the wrong size, its the same wheel and more importantly, it even has the same six-pointed markings in the casting on the backside of the wheel where it mounts against the rotor/drum.
Should help narrow in on what you are looking for.
