1989 E34 M20 - The exact lenght of the shift arm for S5-16

[marko84]

I need an exact length of the shift arm for E34 M20 12V transmission S5-16. I got some shift arms but they're different

lengths so I need to know the exact length. If anyone knows I would really appreciate it. And may I state that it's really

urgent. Thank you all in advance!
