Had a 62 Chevie Pickup. Needed to check brakes, passenger side went fine, but the drivers side was as hard as that lens for the same reason. I had fought with that #$^@!x thing for an hour, heating red hot, cooling with oil to soak in, extended wrench.... and like a vision... I saw the "L" on the end of the bolt. Turning the nut clockwise the nut came off with ease. Live and learn.
The reason for the different threading rotation - some believe it is better to have the rotation of the thread to tighten as the wheel turns, thus as the wheel turns it won't unscrew in the thread direction and lose the nut and possibly lose the wheel. Knew a family in the 60's that told of a story, they saw a wheel whipping past them on an expressway. It was funny until they realized it was their wheel. It can and does happen.
Note: anything that is flammable usually has left handed threads too.
