Front Caster and Camber Adjustment
Caster and camber adjustments are made by means of shims located between upper control arm shaft and mounting bracket attached to suspension
crossmember. A series of convex and concave spacers with flat opposite sides are used. These spacers allow a positive cross shaft-to-bracket attachment
regardless of the number of shims used. Shims may be changed at either front or rear to vary caster, or at both points to vary camber.
