The Stovebolt Site Forums The Parking Lot Tons 'o Fun Dual to single conversion front end question?

I have dual hubs that I am going to look at installing on the front of my '47 single wheel soon. This is so I can use them as spacers for late model wheels. If it works, I may be up for a swap as I have 3 3800s and our son is dragging a 3600 home tonight.

Is there anything I need to be wary of? Spindles are same, right?
