Several years ago I had a tach drive generator off a 1957 corvette come into my possession thru a Auction. I advertised it and it sold fairly quick . I knew it was a very hard piece to find especially since it was a nos piece. I made a wooden crate with semi circular plywood stays to hold it up in the crate . Wrapped it in a very thick high density foam padding then put into a plastic bag bolted the box together and then spray foamed the voids. Put cardboard 3 layers on the box and sent it off. I swear a tank could have drove over it without damage. I was wrong when it got to the end user it looked like a tank had driven over it.
I spent several weeks dealing the the po and was told it was improperly packed . I argued till I was blue in the face. That was the end for me. You could see the skid marks on the box and tire tracks. I still believe to this day it was run over dropped from a high distance.how what when who knows but it made a believer out of me. The buyer was pissed, I was pissed but in the end I was the one screwed. The worst of it was this was a really one of a kind piece that might never show up again. It was a sad ending
