Tom (MX289) did beat me to the punch on the hanger suggestion as well as the vendor. And he was right it looks good that does get it really close to level!
What did you decide to do for the rear hanger, rear position? In order of least to most lift would be the stock C20-30, then 67-72 K series, then square body 4x4 using factory type hangers (each step will change the pinion angle some). Here's a link to the ORD Shackle Flip Kit
