Was just looking in the rear engine compartment and noticed that a nut is missing from the bolt on the air cleaner housing. The nut has a cone shape. I presume I could use any nut that fits but would prefer to find like kind. Any sourcing suggestion would be appreciated. <br/><br/>Thanx.<br/><br/>Update: Got P/N from Donaldson - Purchased from: P119325 by STERLING - NUT.
