Thoughts/do I need to dent my new headers, new pics ?

Good grief guys.

It’s a 73+ pitman and center link. It also has to be a ‘73+ idler, regardless.

You can’t install a center link upside down because the tapers are all directional.

The ‘73+ steering components on a ‘69 K frame is not any kind of “mismatch”, the steering geometry is not changed.

There are slight clearance changes because of the location of the tie rod ends, but, if anything the 73+ arrangement usually creates more, not less space. That is of course body tolerance dependent.
