Not a refund, but a replacement. This type of situation really calls for good advance planning. Further investigation would have told me that my favorite auto glass installer could have supplied the part to me locally at a lower cost. Also, check their prices against those supplied by specialty aftermarket suppliers. In many cases, the specialty shops' prices will be lower due to their volume.
Time is a consideration, too.
Your project will move along at a much faster pace if you organize your parts requirements and time their purchase. Avoid buying everything you think you might need at once. The restoration process is a constantly changing process and requirements change as the work progresses. In order not to end up with a lot of new parts with no home, good planning is the cornerstone to a successful restoration. Saying on budget will also allow you to do more without tying up your cash in parts you can't use or return.
