69 c20 camber issue

[Vortec69]

Hey all. I recently did a disk brake swap on a 69 c20. I used spindles from a 72 c20. I re used my control arms and replaced the ball joints with new 72 ones and replaced all the bushings and shafts also. I also replace the rest of the steering components with new 72 parts. My problem is now I have positive camber on both sides with all the shims and spacers removed. Are the lower control arms longer on 71-72 c20’s? I did have to put the new ball joints in the lathe and turn them down about.020 so they would go in my 69 lower arms so that makes me think the lower arms must be different. Any help would be greatly appreciated!!
