I take it you still have a centre stand fitted ! If so you should of placed the bike on the centre stand on a block of wood (2" high is enuf) and than cable tie the front brake lever to stop it rolling forward, This would have given you all the height you required to move the swingarm to allow fitting of different dog bones.
