How do you shim aileron bracket on rear spar .Mine came with aluminum shims under cast bracket.I assume you want a straight hinge line am I correct.

A straight hinge line is exactly what you want.

One technique is to stretch a piece of thread or light safety wire through all three hinges. Center the thread in the outboard and inboard hinge and look to see if it is centered in the middle hinge. Adjust with shims to move the thread until it is centered.

There are several clever ways to hold the thread centered in the outside hinges. A tiny wooden plug with a slot cut in it will work. A washer and cotter pin will also work.
