Mancinni Racing has the grommets that you want. That's where I got mine, if you need the part # , I can get it when I go back out to the garage.

very nice!! seems to me the breather and PCV are switched around and I'm wondering if it matters? I have always been under the impression that crank ventilation was directly related to crank rotation.
