A little tip...

Always fit the shock to the relay arm first, before you connect the linkage (dog) bones to the swingarm. If you fit the linkage bones at both ends before the shock you'll be fighting against the shock spring to get everything lined up. If you fit the shock first, then all you've got to do is raise/lower the swingarm/rear wheel to get the linkage bones to line up with the hole in the swingarm.

You need to disconnect the dog bones from the swingarm, connect the shock up to the relay arm and then refit the dog bones.

Also, take off all the preload on the shock before you start refitting anything.
