Thanks for the answers. Did a more thorough google search and figured that mine has the "Heater/air conditioning unit" over there. Here's a random image of how mine looks and why I was confused on how a radio could fit there. https://lh3.googleusercontent.com/proxy/2nABIMg7afi6mBvzDhszXEiRA0UBx3AL9Z...

Sorry for the offtopic but I would be very interested to see how they managed to fit that radiocd there.

If you want to make 6th the same as 5th now, you'll need a diff. with a ratio of 0.85 x 3.15 = 2.68.

Isn't it the other way around?
3.15 / 0.85 = 3.7

Encountered the same problem (some time ago) but didnt bother much.
I just cut the outer side of each bolt hole and installed it.
No noticeable leaks.

M42 to replace M40
Z3 steering rack
Remote central locking
Led headlights
New carpets
