Need help with disc brake swap

[1965 Tuned Port]

Here is the problem .I have a 65 1/2 ton that I am trying to put disc brakes on . I rounded up the parts I thought I needed and now I have way to much positive camber . I think I may have the wrong spindles . They have 6 lug rotors and look like the ones on a 90ish pickup . The steering stops on the spindles are so short that the caliper bolt will hit before the stop . I got the spindles , rotors and calipers at a swap meet . I used lower control arms from a 85 3/4 ton . I put in new ball joints in the uppers and lowers . I took all of the shims and even the the thick washers from behind the upper control arm and still have to much camber . HELP .
