71 Swinger Passenger Door

You're best bet for shipping a fender is Greyhound. When I have researched Fastenal, I'm told that it has to be palletized.
Fed Ex, UPS super expensive. I use a bicycle box for a fender and put another box over the out rigger attached to the apron.
Sorry, forgot it was a door. Same thing, bicycle box and Greyhound.
