I've known for some time that the tailgates used in the '65-'72 range and those used for the '73-'79 trucks would physically interchange, although I've been told the body lines would not line up. In other words, the tailgates would bolt up but would look really funky. I've been keeping my eyes open for some pics to show exactly what the differences were, and finally ran across an E-bay auction with what I was looking for. This is a '74 F-150 with a '65-'72 tailgate. I just wanted to post the pictures here for future reference, and in case anyone else was curious.
Now...if anyone has any pics of a later tailgate on an earlier truck, I'd be interested in seeing them too. After all, a picture's worth 1000 words, right?
