If they are original to your car and have no issues I would keep them. If for some reason you ever had to resell the car the would be a nice thing to pass along with it. But that being said I agree that people looking for a full concourse restoration may want them. I look at these cars this way, you can be some one that cares a whole lot about keeping the car super original and deal with the issues it came with, or you can be some one that wants to keep the general form of the car but modify it so fix common problems. I almost would not call this a modification as its something Porsche designed any way.
