Check out Mopar Action's Disco Tech article online, it warns of using that type spindle but many have with no issues. Other than that, you may need to swap sides on the spindles to mount the calipers to the rear for clearance on your sway bar. It's a good article covering everything well.

YES -yes you can.

Holy spit thats a lpt of info it appears the taller knuckles will work with stock uca and stock upper/lower ball joints i also have the moog adsjustable bushings RIGHT ?  thanks  tom

So what parts would be the best set up for my car tall spindels with 12" rotors with sliding calibers or the older shorter spindels with what parts? i have a friend at a junk yard i could have any combination of parts that would work just would like to know what to tell him what parts i would need thanks  tom

Tom "if" you can get the correct A-E body spindles just get them as you will be closer to specification. "IF" you can't then go with the others. NAPA has very nice upgrade beefy rotors I really like if your getting new ones. (check them out)

To my knowledge, nobody has shown proof that either tall or short spindles have any advantage over the other. It has been disproven that the tall spindles cause binding of the ball joint, which is suggested in some early articles. I have found no information from the Pro-Touring or Competition crowd stating that either one is preferable.

Whichever you choose, make sure it is the large-diameter spindle, which is the '71-'73 E-body (?) and the later J-car spindles (Cordoba etc).

Personally, I chose the tall spindles because on paper they have more roll camber than the short ones (which you would expect on heavier cars with softer springs). That choice was purely academic, as I said I haven't found any hard evidence that there is any difference in performance. The tall spindles are easier to find, though.

On one of the A Body forums they explain this issue very well, a search here would turn it up. For me the point is not alignment (easy fix with off-set bushings) it's overall geometry, bump steer and the built in sweep of multiple arcs. Consider you have 2 arcs from just the UCA and LCA pointed to the spindle, then the arc of the wheel as the spindle turns left and right. Add the arc of the outer tie rod as the spindle moves up and down compounded with left and right as the drag link moves in or out in each wheel well. The forces interacting on all this movement at speeds, turning, pulling here, pushing there, the torque of braking is applied to the spindle and transferred to the UCA and LCA....I've read the Mopar Chassis book..... This stuff fries my brain. I'm just playing it safe as possible for myself as Ma Mopar did a darn good job long ago figuring it all out.
