First off, I appreciate all the help. I am working toward an OEM type of engine graft and whatever I do has to be hidden. I have access to machines at a tubing repop company and they think they can make me a stainless knock in nipple for the open "port" in the rear. I can even make a line that comes up higher and routes under the air cleaner base to hide something that will separate the oil and air so I can have my breather hose coming off the Air Grabber base. I will start searching for a separator. Something small, I think.
