1930-1931 AA truck spindles. These fit the large front axle used on the AA only.  They look to be in really good shape.  There is some wear on the steering balls but not bad. They  should work just fine after a quick dressing with some sandpaper. There is just the slightest bit of play in the kingpins.  The pins themselves look good so you dhould be fine with just replacing the bushings or just running them as they are. These use a 1" kingpin and will not fit the car and light truck axle.  Pictures tell the story.
