Anybody use Scarebird brakes front disc conversion kit?

I've been waiting a couple of weeks for info on the rear disc conversions. As far as the pattern goes, I can tell you you'll have to redrill them for the 5X4" pattern, which is what I'll be doing. Size? I don't know. But they are supposed to fit inside factory wheels. They "let" you get the rest of the parts from wherever you want, so you can get the cheapest price possible.
