GMC Pauls and Mar-K both have good information on the bed wood sizes. I have detailed dimensions for a 58-59 short fleetside (hand notes taken when I disassembled the bed) that I could share.

Regarding the comments about dumping junk off shore, I would hope that does not happen, but anything is possible. If it was from a third party I could see that happening, manf or distributor unloads returns to third party who resells as good stuff. Kind of like scratch and dent sales. There is a store in my town that buys all the returns to big box stores and resells them "as-is" at deep discount price. Warrantys are still good but you have to deal directly with the manufacturer to get the junk fixed.
