I wont say it can't be done (cause it can), but I will tell you why you probably wouldn't want to.

there are 2 popular styles of steering wheel mounted shift buttons used on pre-paddle MBZ cars (pre-paddle years are essentially 2003 through 2008). These two styles I will refer to as "long" and "short" (there is a 3rd style that is long-ish AND shifts both up and down, but they are too lame to contemplate).


both the long style and short style "snap" into very controlled and well defined pockets on the wheel (very tough to duplicate).


the short style was used on E55's S55's, and CL55's .... these would be a VERY bad choice as they also require additional (unusual) contours on the back side of the wheel to have a factory fit. HOWEVER, if you really wanted to use this button style, you should make sure and source 1 each of part numbers 870273-0004 & 870273-0005 as they are plug compatible with the paddles (and my paddle kit for the R170/crossfire). These can be found on models built after 2005. The older (2003 -2006 model years) used 870273-0002 & 870273-0003 which are not compatible due to a different switching strategy used in those years on some models (they use a NO and a NC switch with some electronic components rather than the NO, NO set up used in the later models).

the long style buttons were used on SL55's CLK55's, CLS55's, C55's and SLK55's . The problem with using these is that in order to convert these vehilcles to paddles (which then makes these buttons available to you) one has to cut the body of these buttons to make an adapter bezel for mounting the paddle (and to fill the long void in the back of the wheel). ... if however you find these (for less than $108 a set shipped ? which is what the amg paddles cost) MAKE sure they are off of a SLK55, C55, or CLS55 .... IF they are from an SL55 or a CLK55, they need to be from a 2006 (build date) or later car or you will have the same issue I mentioned for the early "short" buttons. The long buttons you want are 1 each of part numbers 870273-0010 & 870273-0011.

worth mentioning, these part numbers (while marked on the parts) can NOT be ordered from mercedes as they were shipped to them as part of the steering wheel (in most cases).

if this is something that you want to pursue, I coiuld send you detailed pictures of what the pockets need to be AND, I may be able to find a set of the buttons ....

EDIT, there are shift buttons used on later models (later S CLass?) that have more of a "teardrop" shape to the required pocket and ARE retained buy a screw ..... so if buttons appeal to you, this may be a good choice. I have a set (not for sale as I keep at least one set of everything) that I can find the numbers off of if you are truly interested.

but, bottom line .... GET PADDLES .... buttons are not worth the bother.
