Droped spindles VS offset bushings

I got a 70 duster that sits about 1/16" above bump stops
Its got big torsion bars, sway bars, subframes, etc
It handles real good with the stock style suspension

So the alinment shop can never get camber or caster perfect,
Cuz its lowered so much and control arms are pushed up...
I kno offset bushings wud be the simple ez fix

But wudnt droped spindles be better?
The only thing that worrys me is the wheel center will be higher in between control arms
Wud that take away from the good handling i got now?
Or mayb increase the handling a bit??
Or no change you can feel??

Im running stock type bump stops ( thoz triangles)
So its a progressave bumpstop.... It dont hit hard

What is your imput???
Thank you!
