I'm putting a 21" rim on the front of the Pan, and moving the 18" rim to the back.
I got this wheel off Ebay (nice chromed and rebuilt OEM star hub) supposedly laced for a Pan or Knuck (would the offset be different for a springer?), but as you can see it doesn't sit centred between the forks. By my reckoning I need to move the wheel a quarter of an inch away from the brake.
Now... can I just loosen the spokes and try to do this in situ, using the axle and forks as a makeshift trueing stand? Advice needed.
