I just picked up a Nuttin Special from a friend and I would like to come up with a new cowl for it. He bought the plane because he wanted the OS 160 Gemini twin that is on it and is selling me the plane pretty cheap. I would like to put my Saito .120 on it but I have to either patch the holes in each side of the cowl or replace it. I thought about putting some dummy cylinders in it but I am not sure where to get them. Any help would be appreciated.
