I bought mounts from one of our popular board vendors and they were made in India. I tried for a couple hours to get them lined up, and my son came home and together, we got three, but the fourth is about 1/8" off. We had a hoist, and tried everthting we could think of from a sling to pry bars. I got a busted lip and chipped tooth out of the deal. We loosened the three hoping that would give us play. Any other ideas how to get in?
