The sway bar should not affect the camber, or a long shot to say the least, even though it might be bent. The sway bar link should isolate it unless it is seriously out of whack.
I'd do as has been suggested and get it in the air, pull the tires, get a good light, and a micrometer, tape measure, and ruler, get under it, and start doing side-to-side comparisons.
If the only part that was bent was the one you replaced, all should be as it was before. Since it isn't, something else obviously must be bent or out of place. Look at it this way, it didn't need the camber-slot elongated before, so why does it now?
Look at the axle and see if the way it sits looks the same as the other side. Look at the way the subframe is positioned and any scrub marks from movement under the bolts. Look at the lower control arm bushing bolts, the angle of the ball joint studs, and on and on. Spend some time looking.
Even a qualified tech (assuming here he knows how to adjust the camber) can miss something that is only off tenths of an inch.
