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.

That would be great for aiming my front mounted machine gun turret,

I'll bet that aftermarket lock actuator works better than OEM. Mine have more play in them than recess in an elementary school.

I have seen a lot of those on old trucks,

I took a set out of my 71 c10 and put it back to stock.
I wish I hadn't thrown them away, I have all kinds of stupid ideas for them now.

Looks like common aftermarket power windows and lock kits I've seen on eBay. I set up power locks in the same way, using an actuator I found on a Toyota in the local Pick-n-pull. Worked great once I got it all lined up properly.

When I went to convert my coupe to power options I bought the factory door lock mechanisms, but when I saw how they were connected I re-sold them on ebay and bought aftermarket. I hooked mine up pretty much the same way and they work better than OEM. At least better than 30 year old OEM actuators.

As for power windows I've seen those kits, but I bought Fiero regulators and installed them. It's not hard, but you need a narrow arm to get all the guts in there where they need to be. Followed the instructions on this site, so it wasn't too bad.

Some people say it's easier to replace the whole door instead of adding power options, but I would disagree. Those doors are heavy and it's hard to get them aligned properly. Not to mention you would have to swap the door skins or repaint.

That's what I did to get power windows on my 88 coupe. It wasn't too hard, and as a bonus, I got better glass (fewer scratches, and tinted). But I still had to add aftermarket power locks, since the replacement doors only had power windows.
