the straight, drive in type are the most common. The threaded hex type go in the threaded holes in the drag link and one goes in the U joint housing. The 45 degree angle/hex type go in the upper spindle ( king pin to some) bearing housing, facing forward. The threaded 45 degree type with rounded shoulders go in the shock links, which you do not find on most AA's. I'm not sure about a 28 AA, some of which had the car front axle. The remaining spots take the drive in, straight type. Sometimes you will find these holes have been tapped, especially in the repro spring shackles. You can get sleeves to thread in that will accept the drive in fittings from many A suppliers.
