There are thin washers that you can slide over the freewheel hub threads to move the freewheel outboard. It appears from the of the winner pro freewheel body that there might be some room left on the dropout side to move the freewheel out a few mm with the spacer. This could potentially make it to where the correct spacer could be used between cogs 7 and 8 and hopefully still clear the spokes too.
