Didn't you relocate your bumper from the factory location which caused all of the issue in the first place? The original Cruise Control Module (CCM) was likely fine unless it was dropped or damaged, which would have saved you the cost of the new one at least.
As far as the labor, $67 isn't bad considering most dealers charge a minimum of 1 full hour labor to even look at a vehicle, which is typically $120+. Regardless, these types of situations are a good of example of where having a working relationship with the dealer can go a long way. If you've bought multiple vehicles from the same dealer and have all of your services done there, they're much more likely to go the extra mile and help you out if you explain the situation. It may sound petty, but in every dealer I've been involved with, the first question the Service Manager asks the advisor is always "Did he buy it here?" and their second question is "Does he have service/repair records with us"? The responses to those questions typically determine the outcome as far as much much they're willing to help.
