I am using a set from Moss on my CB V8, and while I don't know what the
original camber was, I have about 2deg negative now at near stock ride
height.

Subject: RE: steering rack alignment (now shock and camber shimming)
Now I'm intrigued also. Does anyone know what kind of angle change
results from using the negative camber wishbone arm sets sold by Moss
and/or Victoria British? I've perused the two catalogs, but there's no
indication of what you end up with. I need to install new lower A-arm
bushings and I figured since I'm taking it all apart anyway, maybe I
should just swap out the arms while I'm at it. Any suggestions greatly
appreciated!
Thanks,

This is a simple matter of geometry. The lever shock has a base width
of
2.75" between the mounting bolts (left to right), and a shaft height of
1.75" from the mounting surface.
If you install a 1/8" stack of shims under the outer end of the shock
base,
this will tilt it 2.65 degrees, and will move the shaft toward the
centerline of the car 0.08".
The distance between the suspension upper and lower trunion bolts is
8.5",
so this 0.08" inward displacement of the upper trunion will result in
camber adjustment of negative 0.54 degrees. That's not a lot, but it
may
be enough to fix some minor misalignment one way or the other.
If you were an avid autocrosser, and you wanted 1 degree negative
camber,
you would need to shim the outer and of the shock base nearly 1/4" to
tilt
the shock body about 5 degrees. If I was to do this, I would more
likely
use a solid wedge plate rather than spot shims. I haven't investigated
this enough to know if this 5 degrees displacement of the shock body
might
result in running out of downward travel of the shock arm (but I
suspect not).
