Cassette out of Order

[revolve88]

This might be a dumb question/problem...
Today I took my cassette off and I forgot to keep it in order so now the spacers and cogs are all out of order.
Does anyone know how to reorder the spacers (some are different thicknesses) and gears correctly?
It is a SRAM Red cassette.

Yes.

The only spacer(s) that are unique are between the smallest cog and the next to smallest cog - unless you have a 10 speed or a 7 speed.

If you have a 10 speed, there may be a thin spacer behind the largest cog, because 10 speed is narrower than 9 speed.

If you have a 7 speed on a 8/9/10 speed hub, there will be a thick spacer behind the largest cog.
