in an F10/5 or F13WR box. you just have to do some hunting and get lucky.
To actually swap it is a bit of a ball ache, but fun, gearbox out, cluster out, diff out, then all back in again. about a 2-4hr job. But for motorway journeys it makes it over rev at 80ish really so depends what you use it for.
