It would appear that you took the mirror cell apart, rather than just undoing the 3 clips holding the mirror into its cell.

The rubber washers you refer to go between the mirror holding cell and the fixed part which attaches to the main scope tube. The collimation screw goes through them and they perform the same function as the springs found in larger scopes.
