If these bolts were a dime a dozen, we certainly wouldn't be talking about whether to replace or not. They are expensive and FCPEuro has an answer for us. My strategy in replacing them with new ones is to wait until I've completed the final-final-done-done task requiring dropping the reinforcement plate. Otherwise I just re-use those bolts in the interim.
