Lean'n Tony is right. I have sent lots of fenders
back east from California. You have to take them to the depot. They take three days to go back east. Once they load them in LA, it is non-stop.
100 pounds limit, they will take 72" long. Wrap in cardboard. About the same as UPS. You need a city
name (bus station), not just a zip code for quote.
