Are the rings WBD-4? In the ZX-r Manual, if i am not mistaken, the spacers are marked 59. What is the part number for me to get these spacers? Please do correct me if i am wrong. Lastly look at my Optima MId ball diff pictured here, this is the old diff rings right ?

Also i got a suggestion regarding the Lazer shaft with longer spring. After you make the shaft longer with the spring sticking out, how are you going to cover the nut and the longer shaft? I solved this problem with my B4 optima mid slipper, by reaming a hole on the center of my gear cover, then using a chinese medicine bottle, used a hot knife to split it to the length i want, then insert it into the gear cover, placed some silicon to seal it, then superglued it. The result is a B4 type gear cover, with a tight fitting cap that can be removed to adjust the slipper tension, very useful at the track !

yeah its possible to get those but they come in an set with new outdrives also

wbd-4 are the diff washers.
