Years ago, I sold a Ford Top Loader 4-speed Trans on eBay I built a wooden pallet and bolted the trans using the trans mounts with bolts and nylon lock nuts. There was no way it was going anywhere, but in addition I banded the trans down with steel bands. The guy calls and said all he received was an empty wooden pallet. I called UPS to complain, and they said, "this happens all the time, will just have to pay the guys claim". The guy posted a positive response on eBay before he even called me to say he had received an empty pallet. That trans was shipped to a nice beach home in Malibu Beach, CA. I doubt seriously if the UPS driver delivered an empty pallet. If you do ship something, make sure you have them sign for the delivery to help protect yourself. I had three false claims selling stuff on eBay, about 1 out of 10 sales. Apparently, car guys are made up of 10% thieves. The trans was the last time I sold something on eBay, I'd rather throw it in the trash then deal with that.
