Thanks to some advice from friends in Singapore, I had just the shift lever from the BMWP SSK installed in my car i.e. part#

The shift action is definitely shorter and much more direct. It took me a week to get used to it, but once I had CDV it felt perfect. I think it suits the character of the car better than stock, plus peace of mind of genuine BMW part.
It's not tricky, just a bit involved with mid-pipe & driveshaft needing to come out. Pete@Advan (Skycat) is across the install detail and can help anyone else out.
