If I were you, I would call up Dennis and talk to him about it. He might even be able to give you some dimensions over there phone! The plans I have, I'm using on my new plane but from the looks of it the cowl is only 1/16th of an ince away from the sides of the fuse. As far as the fins I have no idea. Call him up, he'll probably help you out.
