Problem solved. As I said, you
might want to file a bit of a flat spot, maybe down to where the washer is supported for most of it's periphery, but there's no real need.
BTW- the fork is strong enough that it's OK to skip the adapter in back. But if you have a plain round rear bridge which takes an adapter, you need it on both sides there to prevent crushing the tube.
