[63burban4x4]

don't know how much this helps, but looking in my box-o-parts, I see at least 3 different lengths of throw arm in my collection............measurements are from the center of the bolt to the center of the hole for the carb linkage. can't say what fits what though, don't know what most of this came from! My truck's not here, so I can't see what came on my original 2-barrel 283, either. My guess is they varied not only by engine, but also by carburator? Since the Q-jet wasn't made yet, you probably just need to figure out what works, but I imagine you already know that! I'm sure you can do a better job than whoever cobbled "D" together! Ifigure I can take the pivot/mount piece to replace the busted one on "C". (I also notice that the accelerator pedal rod is at a different angle, may be a later year of truck? "B" seems to have the throw rod mounted in reverse of "A" & "C".
