I take packing HG's very seriously considering the cost of the part as well as the awaiting customer on the other end. I always plan for some damage along the way which is why I try my hardest to give the box some latitude in terms of predicted travel damage.
That said, doesn't always work out. UPS folks are very tough to boxes and sometimes even HG's don't make it.....like LT's order. I was very pissed about that. But his order was, ahem, slightly different....
