drop pitman arm (again 4-6")
possibly a longer drag link (it's going to have to be moved so it doesn't hit the drop pitman arm)
gonna have to do something to correct front axle caster angle (cut steering yoke from axle realign to correct angle and reweld)
If you have a V8 you're probably going to need traction/tortion bars for the rear axle (to control axle wrap/wheel hop)
I think that about covers it. Why are you so desperate to do a spring over lift?

I agree with 90% of that, the double cardin on the front drive line is not needed, I have soa on my jeep and 4 inch springs and dont have any bind issues, but you have to used sealed u-joints cause the greese zert will get broke off cause the it just wont clear bairly when the shaft spins. So cutting the yokes and adjusting caster wont be needed. But if you were to to put a double cardin on the front shaft I would try it first to see if you'll have the vibration or not. Look at all the 73-86 full size chevys out there who are lifted sky high and have a double cardin on the front saft (all of them came stock with a double cardin) and i dought that they cut the axle yokes and re figures caster angle... I know my brother didnt on his 82 chevy and its soa factory and 8 inch springs and 2 inch longer shackles... and he has not had any vibrations.
so im saying just give it a shot.
