I would rather drive across this country to deliver something than use UPS again.
I sold a complete holly fuel injection system to a guy just two states over. I shipped it and paid extra insurance. I got a call from the guy asking what happened. The throttle arm was bent over and bend the shaft. They said it was my fault. Lets just say I contacted everyone I could think of for help. Ct atterny generals office, BBB and mail boxes e t. No one would help. I ended up buying the guy a new throttle body... It wasn't his fault.
Screw UPS...
Good luck
