ABSTRACT:
A shim system having a first shim with oppositely facing first and second substantially flat surfaces and a second shim having oppositely facing third and fourth substantially flat surfaces. The first and second shims have a relative operative position wherein a) the second surface on the first shim is facially abutted to the third surface on the second shim and b) the first and second shims have a combined thickness equal to the distance between the first surface on the first shim and the fourth surface on the second shim. Cooperating structure is provided between the first and second shims for limiting movement between the first and second shims by relative movement of the second and third surfaces against each other with the first and second shims in the operative position. The cooperating structure includes structure projecting from one of the second surface on the first shim and the third surface on the second shim and a receptacle on the other of the second surface on the first shim and the third surface on the second shim into which the projecting structure extends.
