Rockster real wheel spacer?

[College]

Hi, took my rear wheel off to get a new rear tyre fitted using the Haynes manual as a guide. The Haynes manual refers to a 'spacer plate' which I did not find. Is this because the Haynes manual refers to other models as well or has a previous owner not replaced the spacer plate? Bike seems to run fine and true without the spacer plate. Any ideas? Thanks for your help.

If you do not have ABS then there is no spacer. Its used for clearance of the ABS ring.
