I have done it its easy ,put a driver in the clips they have a hole just ready for it .All parts are interchangeable and replacement parts are on ebay .,Clips just push back on after jobs done. The ones to watch are the plastic ones .I broke two off mine .But that was on my w124 .With the plastic type you need a large G clamp to take pressure off the glass first ,or the plastic clips will snap off as you lift them from the glass , rendering the whole lamp to scrap.
