I'm not looking to move away from my 4 lug bolt pattern just yet but I'm about to pull the front suspension apart for a rebuild and after reading about the H-Body's tendency to push the camber heavily positive in a corner I was considering installing .75-1" taller upper balljoints to help with this.

I have 14"x6" aluminum slots on the front which I hope will clear the upper arm being higher than stock, but my concern is reaming the spindle out too far. Is there enough meat in the 76-80 H-body spindle to accomplish this safely? Do I just go get a S-10/G-body taller balljoint from HOWE and go to town or am I missing something?
