Right hand thread/left hand thread 68 charger????, pressed on drums?????help!!!!!!

Ok, so im helping my brother in law with his 68 charger. We were removing the wheels, so that we could change the brakes. The passenger side of the car went well. When we got to the drivers side, we started getting pissed off. First off, the rim is stuck. Then the stud and lugnut is spinning in the drum, (why the rim is stuck to the car). So....the drivers side wont come off? Front or rear.... So what is it? I keep telling him to stop since we already have one spinning in the drum. That it can be right hand thread?, but he's saying thats stupid, and cant be.. so please help out with this, am i right or wrong. Oh and also the drum is stuck on the other side??? Is it pressed on or whats going on??? thanks fabo!!!
