Positive camber on rear wheels after installing spring relo kit and SS springs

I'm unfamiliar with this.... Did it require relocating the perches on the axle?

A simple angle finder will tell you if the wheels are truly cambered. Plumb Bob on a bare rim, from top edge to bottom edge can too.
If it is truly cambered, and you relocated perches, you could have warped the axle with the welding?
