Chassis help needed ideas?

[Binky.bane]

E36 compact. Basically the drivers side front anti roll bar mount has rotten out and the bush and bracket have broken away from the chassis. What would be the best way to go about repairing this and can you get patch sections if so where from

I just made up a mount out of box section.
Think you can get repair panels from bmw though.
