I wouldn't shim it. The module is probably just sitting atop the bearing flange at some point. Take a careful look and this is where you file a larger radius till it sits flat against the cam. It's possible that just loosening the screws and repositioning the module a bit will let it sit down flat. Filing or grinding it isn't such a big deal. It's not like you're taking off 1/8" or anything. Just cleaning up the edge a bit.
