Default 6 to 4 bolt flange swap on LSD

How to anyone? I'm looking to get a 6 bolt Z3 LSD for 200, but its not 4 bolt like I need.

All I had to do was take an impact and gun the bolt off and gun the new one on. I believe its 30 mm.

I have a 3.15 out of an m coupe/roadster and my buddy has a 3.25 out of an e28 5 series. We had to swap both 4 bolt to 6 bolt.
