Well I am not there yet, but one of my future plans will be to try and incorporate the tailgate latch mechanism from a 67-72 into my 64 tailgate. I think it would be possible to put the handle right under the upper portion of the tailgate just before it goes to single thickness (not sure if that makes sense).
Also, I am not sure if I would use the 67-72 hinges or go with a cable much like the newer models.
I want it to be one of those things (look somewhat original) that when people see it they have to look twice to recall that there should be chains and not the latch assembly.
