If I remember correctly that article stated not to use the later model (late '70's) taller spindles because the upper ball joint did not have enough movement to compensate for the larger angle that the upper control arm would be at. This would be at full suspension compression. Has anyone looked at this? Because if its not an issue, those spindles are way easier to find.
This article, while very informative and full of good info, has been a point of contention for any number of people for a long time because of because of the tall spindle issue.
The fact of the matter is that the control arms will run out of travel before the ball joint runs out of pivot. As a matter of fact, the mopar upper ball joint has so much pivot motion and is so strong that a number of aftermarket, race suspension companies have adopted them for use in oval track racing to this day.
The other argument is that the tall spindles negatively impact suspension geometry. They change, it, whether it is negative or not depends on your perspective. The tall spindles raise the front roll center a couple of inches. This couple of inches means it reduces the lever arm effect on your car while turning, which can be a good thing.
They also are a couple of pounds lighter than other disc brake spindles which reduces unsprung weight, always a good thing.
i think i have solved the problem i found a 72 challenger in the junk yard that has disc brakes ....
Very cool. More impressive than that is that you even found an E body in a junk yard these days.
