Installing electric windows on 1977 230c

Is it possible to change my mechanical window winders for an electric version and what model is it best to salvage all the parts?

 

Evening Julian,

Take a look at these aftermarket products, SPAL. We used to fit these many years ago to cars with manual windows. My earliest memory was the merc 190's.
They utalise all the cars original mechanicals but a gear sits over the winder shaft spline which is driven by a motor. You then add a cover where the window winder used to be.

Good Luck.
