Use composite shims, they won't crush, rot, splinter, or expand like wood shims can. Plus cedar shims are very soft- they're designed to shim vertically, not carry a load horizontally. Use a whole pack or two...they are inexpensive. If you place the shims close together they won't dent the plywood. If you place them too far apart they will get pressed into the plywood.
