Hi, I made a post but it is did not appeared....I'm writting again.
I don't have photos, but it was very easy. We made no adjustments at all. We took the bearings from the old one and fit them to quaife. After a year I still believe that it deservs every poud. I bought it from england and I gave 1050Euros to have it in my hand. I installed it for free. A very big and nessesery upgrade for the car, no contact with the stock BMW LSDs.
