Packing up a stock seat

[Fingerz]

I was going to suggest U-Haul of Walmart, Lowes/Home Depot or a bicycle store. I've used all of these in the past for large boxes without any issues.

It will be no problem finding a box, but check USPS for shipping rates it is the same as UPS but you can get it over night for the same
price that is what I did with Gl1800 seat.
UPS was five days from Virginia to OK.
