Adjustable upper control arm opinions.

Well, it took longer than I thought to get accurate alignment numbers.
Left Right
Caster +6.5 +6.0
Camber -.75 +.50

This is how the car is now with the UCA eccentrics cranked all the way in on both sides. I did not check toe in. To be honest, I have an old Dunlop optical alignment set and didn't feel like messing with it.
I didn't expect the caster to be this close from side to side. I think as of now, it's more of a problem with the car itself and not the UCA's.

Now I can thread it onto the spindle.

That looks like a pretty decent starting point. You just need to finish the alignment.

Get the right side camber to -.5 deg for aggressive/autox driving. Then even out the caster.

Just a WAG, you’ll probably end up with 3-4 deg positive caster. Nothing wrong with that. UCA’s did thier job. You have regular UCA bushing right? Not offset?

Then finish the job with toe-in adjustments

And then double check everything and tighten everything and cotter pins when possible.
