Hi all, does anybody know what the OEM thread pitch is on a Stohr f1000 fiberglass nose? The thread pitch on the nose whiskers that the front main plane bolts to. They look to have never been drilled out or over sized drilled and then tapped but the first few threads are not really great, cant get a bolt into them really easy and I would prefer not to over size drill and then tap. I think if I can re-tap the OEM pitch I should be OK. Thanks all.
