Thank you,
John,
Personally, I would not want anything hitting the seal, too much chance of it getting hurt. The spring cup might not have caused a aproblem if it is located on its od so it cannot move. If the shim is sized correctly and cannot move, it might be ok. I personally put the shims under the spring cup if at all possible.

Like Bill said, -.050 locks would be a better alternative.
