I've had these on my 68 cuda for about 12 yrs with conservative 1.75* positive caster with 16:1 manual steering and only 215/60x15 tires. Drives great!
I bought another set a couple weeks ago and put them on the shelf for my 64 Val. I've noticed the part sources for our old junk is getting thinner every day.
There have been reports that Moog quality has been deteriorating. Happy to confirm the box still says Made in USA on these.
