I checked into this for another guy with a ruby,since the the swingarms are so short. From the pivot point to the center of the axle is 16" and at the swingarm bearings measure end to end about 10.5" or should I say side to side. Its under $200 for the swingarm tube wtih bearings and the rear drive shalf. But you will also need longer brake cables, maybe foreman 450 shocks. Not for sure on the shocks
Hopes this helps
