I do not know how think the hat is, but if it has enough material, .014" should be no issue. You may want to mark the high side and low side just as a precaution. Depending on how it is bent or warped, they may have to take a little from the inside and a little from the outside to get it to run true. Is the thickness the same all around the hat? Can you check?

Something else to consider. If you modify anything made by Wilwood and you have a problem later, you are screwed. Just a thought.
