He called it a shim. I suppose I could look and see what that part looks 'new'. He charged me, like $70 for the part. Sound about right for a shop cost + markup? I plan on keeping that sheet he gave me, and going back in a few months, maybe when winter is over, and getting it checked again, and make sure its not going out of spec over time...
