I got this method from a real starter store (the guy rebuilds them for a living). This is from memory but I think I have it right.
With the starter installed and tight, the teeth on the starter gear should be 1/8 inch from the flywheel teeth. You can measure this with a 1/8 in drill bit. If it is too tight, add a full shim. If it is too loose add 1/2 of a shim to the outside bolt only. You may have to add more shims or 1/2 shims to get it right.
Also if the flywheel is too chewed up you may have to change it. It worked for me first time, hope it helps you.

Ditto's, Dean,Im having the same problem with my 72 ec I just bought.Starter sounded bad so I removed the two shims in it because It looked like it was to far away from the flex plate. may still have to shim up the outside. Rick
