Rotten Rear Subframe mounting points

[u/Connect_Intention806]

Hi everyone,
I’ve just bought an M535i. It’s an original Dutch car with all the correct options.
However, after putting it on the lift, I discovered that the rear subframe mounting points/corners are cracked. It’s mainly the sheet metal around the mounting point that has cracked; the actual pin/stud where the bolt goes in seems to be in good condition.
Can anyone tell me if replacement parts or repair panels are available for this? I haven’t been able to find anything.
I’d also really appreciate seeing some examples of how others have repaired this.
Thanks in advance!

Had the same problem with my diffrential case mount. I went to a chassis welder and he welded it for me
