A little deeper searching turned up this
company. Their website is really old and doesn't look to have been updated recently, but a web check of the company name/address "Bruce Horkey's Wood and Parts 46284 440th st Windom,MN 56101" came back showing they are open and seem to still be active. Their site does list bed wood available for your 1 Ton (see pic below snagged from the site), but my guess is their prices listed there aren't current.
At least it's another one to call and see what they might be able to do for you.
