Well, recently ive had new door cards put in from a newer model which had rear electric windows. And my model of the car has manual rear windows. So now I've come across the fact that I will need to DIY the hole in the door card, which I have already told a friend to help me do some carbon cut out for both sides, real question is; I need new winders now and where can i get a set from specific to mercedes? Maybe an aftermarket brand? At the moment ive been looking at universal ones but worry they wont fit!
