Strut Rod Help Please

Jmo RRR,
The only reason, in my mind for adjustables is more caster, you got that with the uppers.
It was my experience with customers, that if you got over 2.5* + caster, with manual steering, the steering got really heavy, especially at slow speeds in parking lots.
If I required more for racecar application, I'd grind the rear washer stop down to shaft dia.ish, and run a die down to extend the threads, use a nut to make the rear stop, hence a totally adjustable strut for 0$$.
I then adjusted the inner pivot so the arm bushing doesn't bind, and impair up/down loosy-goosy movement .

Now Rusty, like your sure-grip repair, this method is "proprietary", so if you use it, I don't have decals, so make a decal, "Struts by Inertia" no charge .
my .02 . . Good luck .
