WTH are you trying to show.
The first picture is a transmission mount.
The second picture is the trailing arm.
Picture 3 does show the rear LCA which is the only camber adjustable part for the rear of the car WL sells and it looks fine, in fact it looks stock.
Pictures 4 and 5 look like the upper control arm bolts to the subframe which are broken. WL does not make a camber bolt for this. I would be questioning this mechanic, and what he installed. Those broken bolts do not look like any camber bolt I have ever seen.
EDIT: Ahhh, I see now. It is this part.

I would contact whiteline and send them pictures to see what they say. I have a feeling they are going to ask, "what were they torqued at?" It is what I would ask.
