The best combination is like Brian just said. Use a Ford HP housing, which will be drivers side pumkin, cut it down to use stock Waggy axles, and use flat top Chevy knuckles or Waggy knuckles. Some Waggy knuckles are also flat top. Both the Chevy and Waggy hubs will be six lug.
I did this, sort of. Used an F150 housing, narrowed to fit Warn Waggy axles, and Chevy knuckles for the hy-steer. Only difference is that I used F150 hubs and rotors to get the 5 on 5.5 bolt pattern.
The drivers side drop Waggy axle would be the easiest......don't have to narrow it, it's six lug, but it's not high pinion.
