Did you tell him they are cross drilled?
Turning cross drilled rotors will not give good results and normally just ends up breaking bits.
Just buy yourself a high quality set of full face rotors and ditch the "holey" ones! You'll get a small boost in braking performance and a big boost in longevity.
BTW - 4WD vehicles (truck front end normally) have full floating hubs. I'd be leary of this "guy" if he's asking you that...
