All drop spindles (with the exception of CPP's modular spindles) are designed after the 73-87 spindle.
The tie rod holes and balljoint holes are just reamed different sizes.
This is why they can make a different spindle for all the years.
60-62, 63-70, 71-72, and 73-87.

That seems to make sense, but if you look at the parts lists in my post above the 63-70 kit comes with both the upper and lower ball joints from the 73-87, but the 71-72 kit only comes with the upper ball joint. This leads me to believe that the 71-72 lower control arm already has the bigger ball joint. Not sure if that affects the control arm itself, but it would mean you couldn't take a 71-72 stock spindle and bolt it on to a 63-70 lower control arm without swapping out the ball joint or maybe the whole control arm.
If they are 73-87 spindles, is there any difference from a wheel placement standpoint than the 63-70 or 71-72 drop spindles, or is it purely the bore size of the ball joint and tie rod hole that is different? So the 60-87 spindle is all th same except the hole sizes?
