TR2-3 were designed with zero castor; and there is no adjustment for it.  It
is possible to add castor by swapping parts with a later TR4, but that adds
steering effort.

However, steering axis inclination (aka king pin inclination even though
these cars don't have king pins) also causes self-centering, and TR2-4 have
SAI.  Should be 7 degrees according to the factory manual, and again if it's
wrong, something is bent or broken.  You'll probably have to pester your
alignment shop to check the SAI; I've never seen one that would do it
without being specifically asked.

I mentioned once having a TR3A where the inner lower pivot had ripped out of
the frame ... the shop claimed the alignment was "fine" in that condition !
They obviously had only checked toe-in, as all of the other angles had to be
way out of whack.
