tooterturtle: I believe this was a duplicate question from Choctaw. We've determined that he has a Fridgeside type bed (aka wrong bed) on his truck. To the best of everyone's collective knowledge no one makes repop tailgates for this bed.
Just a week ago I found a guy in Seattle who sold me a tailgate listed on Craigslist for $250. When he bought the truck new in 65, he took off the tailgate and put on a slide-in camper. He sold the truck many years later with the camper on it and forgot about the tailgate. He found it cleaning out his storage shed. Red with White letters (my 250 CS/CC is Blue and White) but pristine! So I basically got a 44 year old brand new tailgate...not a scratch on it. A very lucky find.
