Idler Arm Install

Installing the idler arm for the '73 Duster. I don't have the dust/grime seals that go on the tip and bottom around the bushing, so I fabricated some out of a leather pad. They seem to be fine, but I don't like the amount of up-and-down play. See video clip. Is there supposed to be a washer in the stack to take out that slack? If so, does it go on the top or the bottom of the knuckle?
