I do know I need some shims...I just dont know how many for each side or what the angle should be relative to how many inches in shims it is.

cool man keep us posted when you figure it out, i dont want to run into this problem when my kit gets here, i am going to run atlas 6in leafs though so hopefully shims wont be necessary. not sure how i would deal with fluid leaking out t-case ahaha sort of sketchy! have you thrown her in 4hi 4lo yet to see if it all works? also did you clock your front drive shaft by chance?
