Tim:

I should make it clear that 12 years ago when this alignment was 
done, the suspension had just been rebuilt with new bushings, new 
ball joints, bearings, etc.  Actually, additional shims could never 
really compensate for worn suspension parts per se.  With a worn 
front end, you can add or remove all the shims you want but you'll 
just be chasing your tail because the critical 'baseline' 
measurements are different every time and shims can't hide that.

You're right, though
 there's no better way to waste money than by 
getting an alignment done on a car BEFORE you rebuild the suspension!

Doesn't surprise me a bit
 these chassis were manufactured in a 
somewhat crude fashion
 that's why they provided the shim adjustment, 
after all; to compensate for what they knew were fairly loose 
tolerances.

I'd love to hear his input on this
  You out there JonMac?
