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.
I used the existing manual regulator, drilled out the rivets holding he manual crank on after REMOVING the spring( on the second one, first one tried to take my thumb off when I forgot to remove spring) I then made a C shaped piece of metal with the power window mounting hole on it and welded it to the old regulator, I use all mopar parts from a salvage yard. total cost was 1/3rd of what a kit would have cost me AND with less work that using a kit.
Thanks for the info guys, sounds like using a universal motor is the way to go. my next question would be how did you wire it to a switch? can i use any universal power window switch? if possible i would like to use something like the these switches below. I personally like the look of them.
