However, I also found that the other side of the diff was different to the instructions. The instructions show a diff coil spring and #4 washer that is held in place by the diff nut/carrier. But my diff only had a whole series of conical shaped plastic washers in place of spring and washer.

Is this normal, or should I buy a new set of coil spring and washer to replace the plastical conical ones (to bring it back to assembly as detailed in instructions)
