That's too bad John. It seems like this was more a misrepresentation issue, though, depending on how it was packaged, that dashboard could have broke in shipping. UPS has an automatic 100$ insurance for damages but that would only apply if the box had visible damage as they have no obligation as to how it was packaged inside by the seller. UPS rule of thumb is it must be able to be dropped 3 feet and have 150lbs or so stacked on it.
So unless the box arrived in bad disarray, this would be up to the seller to come forth and honor the issue. If he refuses, you can always open an ebay dispute but those can get long and messy so just hope he's a standup guy.
