The only thing I've heard about '67 frames is that they don't have a dimple in them that is required for mounting a power steering box, and some people have run into problems when they try to mount a power steering box on a '67 frame. I had a '67 truck (definitely a '67 because the VIN on the frame matched the VIN plate) and mounted a power steering box from a '76-ish truck on it with no problems, so I'm a little confused about this dimple issue. If a newer gearbox fit on my '67, I can't see any reason why a '67 manual gearbox wouldn't work on a '68-'72 frame, although I have never actually tried. I removed a manual gearbox from a '70 frame, and as far as I could remember, it looked the same as the manual gear box I removed from my '67.
