positive camber

[blackgold]

I just did a disc brake swap on my 70 c10 with 2 1/2" drop spindles. I
Put on a set of 2010 silverado stock wheels and now I have positive camber. I didnt have any before and the spindles are suppose to keep all the geometry the same. So im wondering if anyone knows why this has happened. I did take all 3 shims out of the front on the control arm and 2 out of the 3 on the back. It helped alittle. My guess is that the original springs in the front are just so old that they have saged some and is causing this. I wouldnt think it would be the wheels. If anybody has an idea let me know I would appreciate it. Thanks.
