Well Mr. Ruger I called my dealer today and they said the plastic part numbers is replaced/superceded by the new part which is aluminum so if the shield cracks it will crack on all 07+ bikes. As one side is broken on mine I really have no choice but to purchase the aluminum mounts and hope for the best. I have not seen wide spread reports of cracking yet.
