JBH, that is frustrating. Its hard to trust anybody these days. Of course you certainly want to replace that hardware. I am not too analy about this sort of thing and normally if the bolts looked OK and there is no stretch or necking I would consider reusing.
HOWEVER, NO WAy woulD I reuse such drastically overtorqued hardware from such a critical component that is known to be a weak link. Spend the 10$ or so to get some nw quality hardware and torque them yourself.
Seriously, my car is small
