Rayburn Diff Setup

I have a 2001 swingarm Rayburn, and I need to know where to locate the diff in the rear of the car.

Do you centre the diff by measuring from the the brake rotor to the inside of the bottom rail? If so, are the measurements equal from side to side? My car has the long panhard bar, mounted to the right hand side of the chassis.

When I purchased the car, the diff was located 7/8 further to the left side of the car. I’ve since centred it with equal distances between the rotor/chassis on both sides, and now the RH rear wheel sticks outside the bodywork. Is this correct?

Thanks

I believe they are 1" to the left, measured off the frame rails and brake rotors

36' RR axle tube is 2" to left and a 35" axle tube on the RR is 1" to the left.
