The later spindles are a less than ideal option. Why would you use them when you can source the proper ones
or buy repops from master power?

Eberg has always cautioned against the later pieces, and Mopar Muscle has, IMO, downplayed the effect of such
a swap to save face after recommending they be used.

Using the larger spindles would cause problems with stock/original ball joints. Newer joints have an increased range
of motion but they are at their max with these. With all of the manufacturing issues, who is to say that the chinese
will continue to add in this extra wiggle room or build a ball joint to the specs required to live with these spindles,
specs that have nothing to do with a factory application?

We have had some long, thoughtful, and numbers packed threads about this but moparts mods would never adopt
them into the tech section, so they've all be lost to time. Take a look at the camber and roll center figures in the mm link,
they say quite a bit.

Get the right parts and be done with it. Who solves a problem with a new one? One major rule that I always try to
follow with cars is that anyone off the street should have confidence that the car should operate predictably
should they wind up driving it.
