68 Barracuda Idler Loose

Dumb question....pulled this thing apart today and the sleeve through the bush looks to be the only thing that contacts the inside of the bracket, there are some foam washers that come with the idler but they would offer no stability...I dont have a washer but that leads me to this question...If I DO have the washer, how will it support the arm in the bracket when it looks like the the only solid contact is the ends of the crush tube...Im lost here
