Shipping Body Panels and Car Windows?

Hello everybody, as you ay or may not know, I'm a college age guy that deals with classic car parts as a side business. I have a front fender for a 1954 Chevy Bel-Air that isn't selling locally and I'm considering posting it on other sites or even ebay to get it to move. Also, I lately got in some car windshields, thinking they would sell in a hurry locally, though I still bought cautiously. They for a 1972 Chevy Nova (rear, four door), 1972 Buick Le Sabre (rear, 2-door), 1954 Chevy Bel-Air (side, two door), and a set of front and rear windshields for a 1970 Plymouth Valiant (2-door).

I'm considering shipping these rather large parts but I don't know where I would get boxes big enough to ship these things. Also, car glass must be packed and handled carefully. Leaving them in the hands of FedEx doesn't exactly let me sleep well. Would they have to be put in crates? I'm open to any suggestions you guys might have. Thank you!
