Anyone have good luck with the USPS finding their lost auto parts in the system?

I had a box come apart in shipping, even with tracking they couldn't/wouldn't find it

Hand carry to post office 1
Load in truck 1
Unload at distribution center 1
Load in truck 2
Unload at distribution center 2
Load in truck 3
Unload at post office 2
Load in route truck

I get box, half the parts missing (heavy duty antenna springs and balls), box was poorly taped in the first place, retaped (USPS tape)


Another one

I ordered a throttle linkage rod off eBay, get it, box empty, 1/4" round hole in corner, right through the tape.
I fold a piece of cardboard over the ends of items like this, then tape them to a sheet of cardboard, then float it halfway up in the box with packing above and below.


Another one

I have a lower trunk trim for my 67 Barracuda shipped to be in a 4" shipping tube, the tube was flattened in the middle, it turned out it was folded at least 45^ to cause the damage to the trim. I ended up sending the trim back in a PVC pipe to be fixed and polished and returned in the same pipe.
