anyone put power windows in their 69 dart?

I bought a kit from classic industries to install them in a 73 swinger. No matter what I did I couldnt get the window to go up and down smoothly. When everything was adjusted right it just didnt have enough *** to raise the window. After several hours of messing with it I yanked them out and put the stock regulators in.
The smaller windows of a 4 door would have likely worked fine. There are universal motors you can install on your stock regulators to convert them. You might check those out.
