Probably works fine on regulators after 65/66.  From my experience, the 65/66 regulators are very flimsy and you can feel them flex when you roll the window up real tight, and then they do not stay put.  I'm sure the motor would take some of that issue away, but you still have the flimsy regulators that bend easily.  IF you do it, weld some support to the sides of the regulator arms to stiffen them up.  On the old F-100's there was a Saturn window motor that fit darn near perfect on the original regulators.

I used the A-1 Electric kit on my fastback many years ago and it took out all the rattles and flimsiness of the original regulator because it has its own and it is very stiff compared to the original.  I bet if the original regulators were somehow stiffened so they could not twist or flex, you could make a set that works great from jukyard parts.

the motor on both upgrades is a 94 taurus motor from the rear.. if i remember correctly its the same motor used on the mustangs of the erra.
