Hmm, I'm seeing some familiar equipment there. My '69 has the cable & bracket set-up like the last picture, but without the kickdown cable (3-spd man trans). That also requires a different gas pedal ass'y but if you have the whole set-up, it's very easy to install in a '68 if required for a 200/250 swap or a later 200. We actually went with an '80 Fairmont 200 (3.3ltr) when my daughter's original 6 finally gave it up; and the linkage to cable conversion eased the install process.
Having said all that, I clearly remember my '69 having a bracket and clip to retain the fuel pipe to the front right corner of the valve cover, but not the vacuum hose (not a pipe). I cannot tell you if I had a vacuum pipe; would the clip have held both pipes. I can also say that the valve cover from her '68 fit just fine on the '80 engine, so things didn't change through the years, at least.
