True. And unfortunately the chassis was manufacturered incorrectly (or
arguably, the A-arms were manufacturered incorrectly) so that in practice, it
was impossible to achieve the factory specified caster measurement. That's
why 1972 and later cars were issued with different upper front A-arms,
which allowed for more caster (although still not enough).
At a minimum, you should mill .100" off the back side of the upper ball
joints. This enables the spindle to be tilted rearwards, increasing caster.
On a '71, that gives you 'almost enough' and on a later car, that gives you
'barely enough'.
Mike (living for the moment with 'barely enough'; with milled ball joints
on my '72 I have 3.0 degrees on one side, 3.1 on the other)
