I had all sorts of trouble with my passenger side outer rocker. When it comes to how the new metal fits, anything is possible. You can check out my build thread for examples of how I had to slice mine up.

I wanted to second that you should use the parts that you have at your disposal to determine what part is out. You have the door, use that to check the opening and gaps. You have the other side, use that to determine if the front cab support, rear cab corner, and other points in the frame are out of alignment. If the inner rocker has been replaced, it is possible that these points are spread wider. You can also use the old metal and the other side to determine if the new rocker has the correct dimensions. In my case, you can see in my thread, that mine was way out. I had to slice, hammer, bend, patch, and re-weld almost every part.
