$75 USD + exchange of your stock cover for the aluminum ring
$100 USD + exchange for the colored anodized ring in blue, red, or Gold.
I also have brand new never touched oil covers in hand so if you are thinking about keeping your stock cover... I can make you up a brand new one $140 for an aluminum ring, $165 for any of the colored anodized ones.
