That's the reason I cautioned about using them, because I knew you
didn't have a clue about the use of different grade bolts. I suggest
you read up on metal grades before suggesting someone switch bolts on
anything. The one thing I've seen the most mis-used in my years as a
mechanic is grade 8 bolts.
