67 firebird with dropped spindles/alignment specs?

[moparcolt]

I have a 1967 Pontiac Firebird with tbular control arms and tall 2" dropped spindles. I got all the parts from Heidts Hot Rod Shop. I am taking it to get it aligned and I was wondering what specs to use? I know the taller spindles change the geometry so where do I even start with the alignment specs?

The rear is a 4-link with coil-overs if that matters.

Thanks, Chris
