A few questions on my new A4

Hi guys, a few more questions:

Per previous post, Just bought a '98 2.8L A4 5spd.

1. I read online that this car has the tosen diffs with electronic diff
locks. How hard is it to install a manual bypass for these? I LOVE the
ability of my 4000Q to manually lock diffs - makes the car hella more fun on
gravel. And before I get lectured on it - yes I know the dangers of driving
on pavement with locked diffs.

2. I didn't get the book with my car and the fuel lid says that the required
fuel octane (R+M)/2 is 87/91. WTF? Is it 87 or is it 91?? I see that it's a
10.5:1 compression motor, so I am inclined to think that to my regret, it
will want 91 Octane, but is that right?
