positive camber disc brake?

[peelintire]

Hi all;
I need a little help. I had my truck 64 c10 converted to disc brakes using -
1998 spindles and 81 lower control arms. Recommended on this site. the problem is my camber is out 2.2 degrees, any one no the problem, and how I can fix it?-
I know I can use 73-87 spindles, but I have to get lots of other part to change over. will 71- 72 spindles be easier and less work/$ only need upper ball joint, but newer calipers will not fit. want to stay 6 lug. I am pretty sure the spindle is the problem!

Thanks
