If you really want it lol.
It's not in the best shape and it's not threaded, my guess is that it snaps onto the BMW shifter.
I couldn't get it to turn off so I pulled really hard and it popped off and I got a black eye. I would've been more careful but the junkyard was closing so I was walking to the front to pay for my other parts when I saw it so I had to act fast.
