they usually come with adapters to fit most cars .
but the down side is you would still have the winder shaft sticking through the door ,
I know that there will be a cover to go over the shaft but it wont look as clean and smooth as the factory windows with a blanking plug ,
also your mechanisms will have to be in tip top condition and wind up and down very smoothly otherwise you will risk burning out the aftermarket motors.
I used to have aftermarket electric windows on a mk2 cortina in the late 70's ,
they were really cool until one day when the motor didnt work and smoke started pouring out of it
