Well, It all depends. My dad had a 450SLC, which is basically the same car with a fixed (non-removable) roof. Anyway, we always used Trico blades, and they used the same part number for both sides. When I got a set of Bosch blades for my 86 560SEL, they were the same part number for both sides. However, the Bosch blades were black and looked just like Trico's, so unless the ones you are getting are different (which is highly possible, Bosch typically has at least 2 variations of everything

) you may end up with similar looking blades. If you are a real Original Equipment Traditionalist

then you might see if you could find a set of OE style on a salvage SL of the same era, and then putting American Aftermarket Refills in the blades. Just a thought. Thanks, Dave.
