Need advice help.

You cannot mix 73-76 parts with 67-72 because the taper on the center link is different. One style has the idler and pitman mountimg from the underside of the center link and the other style has the idler/pitman entering from the top. I don't know for sure if using 73-76 lower ball joint/steering arms with the 67-72 center link junk affect the geometry or not. I was pressed for time right before the Nats and did not have a 73-76 centerlink, idler or pitman on hand.I.

To confuse this issue, it's not strictly a matter of "year."

There are only 4 parts in this which must "match."

The whole deal is caused by the change in larger spline / later model steering boxes

So the steering box spline must of course match the pitman

The idler, pitman, box, and center link all must match.

I actually was running a late K with early pitman, link, and idler on my 67, and when it goes together it will have a large spline power box so the "new build" will have the later pitman, idler, and center link. This does not affect geometry so far as I know. Many guys have swapped lower arms early to late as well as lower ball joints. (steering arms)
