Need steering suspension help from the Bada$$'s here

Well, in your second to last picture, the centerlink is upside down... The "drop" in the center should be facing down. Just pivot it at the tie rod adjusters.
Another thought- your old idler and pitman arms are '72 and earlier pieces, since you're replacing them with '73 and up parts, I hope you got a '73 and newer centerlink, too- otherwise the tapers aren't going to jive with the new arms...
