That is a poor excuse from Univair and I would have considered sending it back and telling them to send another one. This is mounted on a Continental engine on a McCauley prop and it doesn't know if it is on an Ercoupe, a Champ or anything else. The only part of this install that has anything to do with an Ercoupe is the clearance between the back of the spinner and the nose bowl and there I will admit sometimes it is hard to get proper clearance so it does not rub the nose bowl but that is not where you said you had a problem.
