I cannot answer the exchange question but there are at least a couple of companies that sell reproduction beds for a lot of trucks.
The name of one of the companies is: LMC Truck and another is K-Mar. I don't have either address with me at this time but I will return to the forum and provide those for you. My recollection tells me that a new bed will be about $1100-&1200.....but,, it will be wrinkle free. It's hard to get them that way when they are 41 years old. Hope this helps.
