Easier said than done, given that the suppliers of modern digital alignment racks continue to include factory settings which - as has been mentioned time and time again here - are not usable for radials. Not unless you want to wind up in a tree, anyway.
Happy Mopar owners having their cars serviced at Mopar dealers isn't exactly a good sample size, especially since - 50 years later - there's no sign of consensus regarding B-body geometry, only fervent schools of thought in direct opposition.
"Easy steering" is a vague (irony not intended) term and has multiple interpretations, as is "old car" steering.
As I mentioned in my original commentary, the 3-turn variable ratio Saganaw side-mount steering box in my '71 Mustang and the other 4-turn Saganaws I've experienced in 1970's-era Fords and Craprolets all meet the definition of "old car" and "easy steering." They're light and can be turned in with little effort. However - in my opinion - I wouldn't call them "sloppy," and in my experience, they are definitive in directionality. You turn the "easy steering" and - for normal street driving - it goes exactly where your brain estimated that amount of steering input would place the car.
I have nothing against this "old car" steering and I like it very much.
The Mopar box can just as easily be called "old car" and "easy steering," but not anywhere on the same level as the Saganaw box. I would absolutely classify the feeling as sloppy, excessively light (i.e., the shaft is not connected to anything light), and extremely vague. This isn't my assessment of a Mopar A or B-body with bias-ply alignment settings (yes, that experience is in my wheelhouse), this is my assessment after nailing down a correct, modern alignment with proper caster and camber.
That type of "old car" steering I can do without.
I'm inclined to believe much of the lore that has been passed down to these days around old car experiences comes with a caveat of single-brand loyalty, so these experiences - even within the same era - are sometimes not representative of the era. Heck, this even applies for late model vehicles. An LX or LD Charger rack doesn't feel the same as some Kia/Hyundai racks of the same era (though similar), and if the regular driver of either were to step into a BMW of the same era, they'd discover a much stiffer beast.
Incidentally - side note - similar side-mount Saganaws to the Fords were fitted to Dodge B-vans after 1994 and up to 2003 as well. While the springs in them are tuned to provide more resistance to turning, the general directionality and self-centering is on par with the 1970's Saganaws. They may not have the feel of a power rack-and-pinion, but somewhere, someone at Chryco - prior to DamilerChysler - decided that a Saganaw box designed back in the 1960's was fit for a vehicle of the 1990's...and the Mopar box wasn't.
