So I purchased the entire wiper arm and dismantled/removed the rubber blade from the new blades to only use the rubber blades and rails in the OEM CF wiper arms and tossed the Traco arms. I have some notes in my CF file that indicate a Traco "Exact Fit" 46 series "narrow" blade. Not sure if the notes are accurate but are what I saved after the wiper arm purchase adventure. I recall the swap was not easy. I have only replaced the rubber wiper blades one time in 3 years owning the CF. The entire process was time consuming but was achievable to keep the OEM wiper arms, especially the driver side that has the "spoiler". The wiper arms were not that expensive so none of this will break the bank, but WAS time consuming. What else is new with the CF. Oh yes, I called Mercedes parts and used a VIN number from from an SLK 320. The price of the blades were ridiculous but I only made that call to see what the shortest route may be to obtain new blades. The Traco 46 narrow series fit the OEM arm (if my notes are accurate). I'm sure my blades may need to be replaced in the spring so I'll be doing this all over again. Look for Traco and prove me correct. Hope this helps!
