I dont' believe that aany of the adjustments will help with the problem your having. I also have a 67 with power top and I have the same problem. Make sure you have the 67 well liner. Also when putting the top down it helps to arrange the folds so that they will lay as flat as you can. The material tends to catch between the bows. Doing this will also help prevent the pinching the top casing holes in the canvas.
