Hope this is not true. Moog Offset Upper control arm bushings.

These cars were targeted to family, little old lady, shopping vehicles, like the Novas, Comets comparables. Performance wasn't the target.
The factory caster specs were near 0, I believe some were Neg caster, like a shopping buggy front wheel, you know how they track.
You crank in a buncha caster into a little old ladies car with manual steering, and she won't be able to maneuver in a parking lot, it just takes so much more strength to turn the wheel at slow speed, and she'll let you know about it ! ! - lol
The offset bushings let you get to + 3*ish degrees where +2 was generally max, if lucky .
3* was such a vast improvement .
5* is kinda like putting a blower on a grocery getter, but with power steering who cares, the power steering lifts the car .
