Supercharger rebuild question

[mulderab2]

In the kit there is a “spacer” and a “washer” that are very similar.

The spacer goes on next to bearing and large spacer. The washer goes in between charger wheel and castle nut.

Only difference looks to be thickness, one is about 2x as thick as the other. I’m assuming the washer is the thinner of the two

Does anyone know if I am correct?

The thinner one is the spacer. The thicker on goes between the impeller nut and the impeller.
