Thanks to modern technology (iphone) I am typing this from a parking lot, stranded in my 67 waiting for a flat bed. I was on the highway at about 70mph when I heard a loud bang and the car started shaking. I got it to a parking lot. My TH tranny grinds when in gear and the car rolls while in Park. My guess at this point is the front U joint because but who knows. I was just bored waiting for the tow and wanted to post. At least it is not raining however I am in a not so good part of town. It would be funny if someone tried to steal it and the car would not go anywhere!
