I live in Pennsylvania. It's got about 129,00 miles. The garage had it up on the rack and didn't see any other issues, but I definitely did not want to pay for factory parts. Now I'm looking at $80 for a $5 bolt. I appreciate the response though. It seems odd that both sides would show the exact same wear at the same time. I don't suppose it could be the shocks?

Can anyone identify these bolts for me? My rear wheels need to have the camber adjusted because the inner part of both tires is getting chewed up. Once we got it on the rack, we found that these two bolts are seized up, so I need to order replacements before we start trying to remove them. An official description would help, but a part number would be great. I looked at the exploded view of this and I can't seem to identify the right ones.
