I used these Mopar P5249642 for the grommets on my aluminum BB covers.

THEY ARE OVERPRICED ON EBAY , i MADE MINE OUT OF AN OLD TWIST ON BREATHER , U CAN ALSO DRILL THE BLANK SPOT OUT AND INSTALL THE CORRECT SIZE RUBBER GROMMIT AND PCV VALVE FROM ABOUT ANY PARTS STORE -
I drilled and tapped mine , and used an alum fitting for a second pcv valve . A DIFF MATRIAL LEAKED , Had to use alum. on the alum. cover .
