pitman arm, parts needed to mount ?

[74 dustaar]

I have a 1974 duster and went to get a front end alignment but was turned away because my pitman arm is missing 2 washers. 1 top and 1 on bottom of the mount, Are these a special size (thickness) ? I went to Mancinis and the new moog part did not come with the washers. What size do I need for a replacement Thanks

maybe they meant 'idler arm', they have washers.

they can't set a good toe with the idler flopping around.

the pitman is pressed on with no washer.

Yes, it is the Idler arm. So any idea what size these washers should be ? Thanks
