Hey there Dave; as rightfully disappointing as your initial response is, perhaps cool off a bit with a favorite beverage and take a breather. Can you easily ascertain what the part is and where it was located? If so you may want to consider the feasibility of repairing it yourself and avoiding the risks and pitfalls of trying to return it if it must be packaged and shipped. Especially this time of year. We've all seen the videos of delivery drivers (of all kinds) tossing an obvious boxed TV set across a fence into a yard. Why subject your prized locomotive to such adverse possibilities!
If you bought it from a local shop, this is a mute point but only a suggestion sir. :-)
