changing front E 165 bolt pattern to F 170 pattern
 

What is the best way to switch to the F series 8x170 front bolt pattern. The rear is easy as I'm getting spacers that will do that. but what about the front? I have a few salvage yards near me and need to know what to grab. They have a 2005 F250 but I don't know if the steering knuckles are able to be switched over, that would come with the bigger discs as well as the new 8x170 bolt pattern. Would that work?
