Negative camber?

Good day/evening to you all,

Still fixing up this 1994 4WD KZ I bought back in February. I noticed that it was pulling pretty hard to the right, so I checked tires and pressure on arrival but still pulled. I kind of assumed it was not aligned, being a japanese import and our roads here in Canada being flipped and all.
I since fitted new tires and went to my mechanic to get it aligned properly, but he spotted that the front passenger tire's camber is way off relative to the driver side (as in the top of the wheel is pointing inwards). He tried to adjust it but said that something suspension or steering related must be bent or damaged. He's quite busy and off on vacation so hasn't had time to work on the van properly, so I'm asking you all for advice. What would be a culprit for this much negative camber, and what do I need to replace?
Have to admit that I'm pretty deficient when it comes to suspension/steering stuff... I just don't want to cause crazy uneven wear on my tires, plus I'm not really confident taking it long distances.

I'll try posting a picture of the alignment report tomorrow for reference.

Many thanks it is much appreciated

camber bolts can get rusted inside lower control arm bush.....preventing adjustment... if a pneumatic hammer or sledge hammer won't free the bolt then bolt must be cut
