Modding c4 shift kit to fit FMX

whats up everybody. a while back me and my dad were putting a ratchet shifter into the car and found out it was the fmx. we tried to make it work by making some parts and whatnot but gave up after about an hour of trying to get a clip over somthing and holding a bolt etc etc, one of thos "no space" areas.
anyway i was wondering if anybody has tried this or knows how to?
i really would like to get this...
