Chris,

one of the factors to making inserted bearing work properly is the deterministic nature of the design. The rod, or block bore is to a specific size and round within tolerance. This is done to make the insert pair conform and crush for proper retention, and resistance to spinning. By adding shims, you are in effect distorting the bore and more than likely will cause problems. I am quite certain that the AER rods are precision machined and sized for the bearing inserts. It is probably best to contact AER and get the bearing size information and then determine the course of action.

As I mentioned earlier, checking the radius clearance is paramount and not hard to do.
