Anybody having any trouble with the wiper posts being too short. Fully assembled not in the body there is only one thread showing. This is leaving no space for the body thickness for installation. I tried to reduce the length of the spacer under the body but that only leads to the gearbox making contact with the underside of the fiberglass and changing the pitch of the post. It seems like the post is too short for the intended job. I might have to go to finish line and see if their posts are longer.
