Just use a centre punch and on the broken section of the bolt and drill into it(use 8.5 or 9mm bit), try and keep it central as much as possible, you dont even need the thread in the swingarm, as there is always a locking nut on the bolt, so a hole that is slightly bigger than 8mm is cool that way your bolt will fit straight in it, id even drill out the thread on the other side and it will never seize if left unlubed for a long time, just make sure they are tightened properly after tightning the axle.
