In a simple form if you take the wheel off the front you can observe that t=
he upper ball joint is more rearward than the lower ball joint.  That is po=
sitive caster. Between the upper surface of the crossmember and the lower s=
urface of the =E2=80=9Cframe=E2=80=9D rail is a wedge that is higher toward=
s the back.  This assists in moving the upper ball joint more rearward. Add=
ing additional =E2=80=9Cwedge=E2=80=9D increases the positive caster. Howev=
er, there is a limit to the wedge because a straight bolt has to tighten th=
e angled crossmember to a flat surface.

I was also told that the fulcrum pins (not sure if it is upper or lower) ha=
s an offset bias and inverting it front to back (or visa versa, not sure wh=
ich way) can increase caster.  Whether the statement was made just to make =
a point, or it is actually a practical means of adjusting caster..., other =
who may have done so will have to tell you.

                The offset you mention is shown in the Shop Manual.

Section F, pg. 22                lower fulcrum pin             1 =
1/8=E2=80=9D spacing to the rear of the lower A-arm

=20

I=E2=80=99m not sure what the dimensions are for the lower fulcrum pin =
or if that can change the caster.

Maybe someone else on the List has better knowledge in this area.

The way to adjust caster is with short shims under the upper a-arm 
mounting bolts.
A shim at the rear bolt would increase castor, under the front bolt will 
decrease.
Picture that upper ball joint movement like Tom suggested.

The lower fulcrum pin can be installed backwards to increase castor.  It 
is a pretty large
increase I think.  I have only seen one car (Ken Mattice) with that done.
