Anyone know where I can get a kit to convert manual to power windows?

I don't know what vehicle you want to put them on but check here to see if they have what you need.

FYI....power windows do fit in a manual door. no modifications needed since the holes have already been punched..as well, theres a little hanger where the motor sits on which is the same for both. so its a bolt in adjust and go.
