Caster & Camber VS Height

I have a 1965 Barracuda that I've upgraded from 9" drums to 74 Duster disc brakes and used urethane UCA bushings from Just Suspensions. I don't have power steering. Having read up on the alignment advice here at FABO and at slantsix.org, I want to my car to have:

I've been having a hard time getting the local alignment shops to adjust to my specs. I know that, as the torsion bars are adjusted to raise the ride height, camber becomes more negative but, on the alignment rack, raising the height seemed to make camber more positive. The front is adjusted a bit low (much less than the 2" factory spec) at this time.

I bought the Moog PN 7103 offset bushing kit to get more caster & camber adjustment but I'm wondering if the real problem is that the alignment mechanics don't understand a-body suspensions. I have a new idler & pitman arm to install this month and would rather not replace my UCA bushings unless necessary.

Can I get -0.25° camber and +1.25° positive caster with my already-installed concentric urethane UCA bushings with just a bit more ride height?
