In between rain showers I got the bearings and bushes out of the swing arm. They were in pretty good shape but I have new ones including much higher quality bearings, there is definitely signs of the isolators collapsing, the new setup is significantly different. There are various videos of aligning the motor while fitting the rear axle but having examined it it can only fit one way, there is no left and right alignment other than allowing the rear of the motor to slight shift depending on the front upper and lower alignment mounts, once it is bolted up it will assume a neutral position.
