The knuckle should move quite easily left and right, but doesn't move up and down with the strut bolted in.
Basically what i did for mine is have the knuckle mounted as it normally would be, then have the strut out on the ground. I used a die grinder with a funny bit on the end for cutting sideways and stretched out the holes in the direction i mentioned before. Then put the lower bolt in the strut first thru the knuckle, then push on the strut and the knuckle should locate into the strut mount, then bolt it back together. This was on OME struts that i did this that already have some adjustment made into them. But with the knuckle completely against the strut, that's the maximum camber you can get there. I didn't touch the lower bolts because it didn't need it. When i took it to an alignment shop, they were able to get some adjustment out of the tie rod ends to help set it nice and straight, and it all worked.
When mine gets lifted off the ground, then set back down again, the camber looks horrible until you drive it down the road, then it straightens out.
Have you been to an alignment shop yet since you slotted the upper holes?
Something else i just thought of... Unflip your upper strut mounts if they are flipped. It might have a negative effect perhaps on the camber.
