I'm speaking based on my 11 years of experience within the company. Every set I've sold required changes to make them fit- an issue people on [forum-name] may or may not be aware of since most members don't complete their own installations. If you're up for the challenge, I can surely get you a set, but because I know the issues, the sale will be final, regardless of how much labor is involved in making them fit properly, even if you have to spend 15 hours re-making them. They very likely will not require that much time to correct, but I don't stock them, nor do I sell them here because I know they don't fit 100%. These were originally designed on the W211 chassis (which the CLS shares), but the CLS steering rack location/geometry is different than the W211- just different enough to cause problems with steering shaft/header clearance.
