The silver Formula I bought recently was converted to power windows. I could also tell from the feel of the lock mechanisms that it had aftermarket power lock actuators added, although they currently don't do anything.
The inner door skins have a plug where the window crank used to be. (I need to get some door pockets.)
I was curious, so I took off one of the inner door skins, and found a strange sight...
The windows are operated by a gizmo that actually turns the manual crank shaft.
Below is how the lock actuators are mounted. I personally wouldn't have done it that way, but perhaps they will work OK when I wire them up.
