Paul brings up a good point about your reasons for the double discs, Mark. If your motive here is primarily to increase the effectiveness of your front brake and not just for aesthetic purposes, then it would be much more cost-effective to just find a nice 4 or 6 pot caliper which would fit our bikes and bolt that right on, than to go to the added expense and work to find that somewhat "Unobtanium" T-Bird Sport hub, the extra Speedmaster fork leg to bolt the other 2-pot caliper to, the new brake lines, and the lacing up of that hub to your BA rim.
