Rotor spacer

Hi All.
There is a spacer between rotor and crankshaft sprocket?.
AN supplies now 03.0251 3/8thick and diameter 1.1/8.
In another topic i think to have read thath dont need spacer.
Thank you.

O32051 spacer is used on both P11 and G15/N15 to space the rotor. Atlas uses a different spacer.
