I have a 2008 128i manual.
I wanted the 3.7 r&p so I also have an auto from a 2013 with only 28k, It's 10 bolted.

What can I ask the seller so he can measure to make sure it will fit. I'm ok with grinding the pumpkin if I need to.

This listing has them all the same internals.

The ad says the maker of the diff is 3J Drivelines out of the UK. Maybe they can help if the ebay seller isn't sure?

Based on my own research, it should fit - from the application notes on Diffsonline wavetrack fitment:
