For attempting that route in the past - yes you can hook up any shifter to a FMX with some fab work. The only difference between the FMX and C4 or C6 hoook up is it is reversed. There is a guy on this board that showed some pics of how it was done to his car (Previous Owner did it for him) But in my opinion it didnt look too solid. Do FMX shifter search and you can find the thread with pics.
