Andy, I think that was covered in the old Mopar circle track and the performance manuals...

Now the big question is can I use the '73 center link with the '72 lower ball joint? It all fits but there is a lot of angle on the tie rod since the inner taper points down and the outer taper points up.
I could remachine the lower ball joint so the taper points down but that is a lot of work. Ok. Didn't think there was a width difference between the center links. The 73-76 LBJ also has the tie rod taper pointing up. What's the geometry difference between the 67-72 disc and the 73-76 disc LBJ's (steering arms) ??

Would be interesting to have an adjustable center link like thir ines we used in circle track racing. Mopars center links are non wear...Less expensive to build/design. Like this but pitman and idler to the inside of the tie rod pick up points Then you adjust with these slugs

Tie rod end design changed for the 1970 model year.
In other words, '70-'76 tie rod ends interchange, but they are different than the'69 and older version. But the centerlink didn't change until 1973.

if you move the outer tie rod to the top it will have more bad bump steer

Which of the two center links is best for optimal handling when using the 73+ Disc brakes and ball joints?

Need to do it on many cars to confirm a trend. There are other variables effecting the bump steer. Alignment, suspension parts used, alignment adjustments, straightness of frame, production tolerances may all, some, or one effect the bumpsteer results.

Aren't the lower ball joints different, too? If the tie rods are the same length between the two styles because the tie rod mount location on the ball joint is relocated the same amount that it is on the drag link, bumpsteer would be the same, right?

So this makes me curious about my car, I have a '70 Duster that I upgraded to '73-up spindles and brakes, if I'm still using the older-style steering centerlink will that cause bump steer issues?

No “issues” It will be in an acceptable range of a stock setup. Very few of these cars will have the same exact bumpsteer to the 0.001 inch.
