I think the shims he's refering to are approx 1/2" disks with 3 holes
for the studs and a center hole for the top shock bolt to protrude... at
the top of the front springs between the top spring plate (round with 3
vertical studs) and the upper suspension-frame spring mount.
The shims otherwise referred to are to adjust camber, as you stated
