Alignment - it can't be done?

Looking for the basics of alignment.
67 Barracuda, factory disc, manual steering, front suspension gone thru, I forget the kit and/or parts used, but definitely from fabo advice.

I was told my car cannot be aligned because the offset washers aren't offset enough.

I'm not buying that, however I want to buy new tires, but before I do that I need to understand alignment basics.

Reading thru various threads, my understanding is these upper bolts and washers, not sure of the name, tie rod ends, and torsion bar adjustment, all play a part in proper alignment.

Am I missing any adjustment?

What are the adjustments that can be made with each?

I don't believe I have any issues that would prevent a proper alignment, but are there any potential problems to be aware of?
