Dana - thanks for the pictures, that is a great help. Now, do the arms get 2 stub washers per bushing/frame connection or 1 each?

Dave - I personally have not dropped the arms, but they have a long history. They are early arms, from frame #308, attached to vin #712. I knew they had the same part number but I still thought I should ask. The difference in question is that tab of steel on the inside portions, one tab is longer than the other. Picture to indicate what I mean:
