Yes it is possible but it would have to be bent pretty bad. Adjusting those window is a bit of an art in that what each adjustment while you know what it is supposed to do, typically works backwards from what you brain is thinking. Additionally, every adjustment affects every other adjustment, it may be possible that your window is canted fore and aft to the point that at the point it cannot pull in at the point you are having issues with. Its hard to see without seeing it and even then it takes a lot of patience, adjustment, readjustment, etc. The angles of those windows and the body are a bit complicated, I have on occasion backed off all of the adjustments and started over. From the sounds of it, your window is either canted or slide too far forward (doesnt take much).
Have you stopped by any body shops or better yet connected with any local Mopar clubs where you might link up with some old school Mopar guys who could help you?
