Here are the new shifters on my 2010 Z4, I didn't take snaps before the install but here is where I ordered from. It was a 30 minute install, BMW was whining to do it so had it done at a friends garage.
Also got the nicer pedals

Sorry for the poor picture
Edit: You don't need to unplug the airbag, that might set off codes but, do unplug the battery as a precautionary measure.
