I have recently lost my bracket axle unit of my XT 2016 m8000 rear derailleur. My friend will be mailing me his XTR 2016 di2 bracket axle unit. Is it compatible/will it fit? I just wanted to know before i buy an after market bracket axle unit from(Goat Link by wolftooth components).

Here is the Shimano Exploded View PDF for the Di2 mech (pdf download):

And for your XT one (pdf download):

What you can see from those documents is that the Bracket Axle Unit aka B-Axle is very different between XT and XTR Di2.

I would expect them not to be compatible.
