Jim, I don't have a photo, but the 3 different trunnions (0 degree, 3 degree
left, 3 degree right) look virtually identical.  To see the difference, you
must look closely at the angle between the pins that stick out, and the
threaded bore for the vertical link.  With the 3 degree versions, you can
just barely see that the bore tilts a bit relative to the pins.  If memory
serves, it tilts to the rear (of the car).
