What Pitman arm etc do I need for this setup?...

The pitman arms are the same on the 68-72 cars regardless of power or manual steering.

The 73-76 pitman has different part #'s for manual and power.

Thank you. And you know, now that you say this, when I look at the PST catalog, it makes sense, since for '73-'76 it says it costs more for the manual steering one, but says nothing like that for the earlier Pitman.

Looks like this is mostly settled unless anyone has any advice on whether I should replace that Pitman arm or not... is it really that high-stress of a piece that I should replace it no matter what?

Again, to everyone... thanks for the help.
