KR250a1 case repair?

[glidercoach]

I just finished documenting all my spares! I have a new case half (engine ID side) and a used other side that has a loose insert for the main bearing from a crack. is this repairable? I have almost enough parts for a complete engine if I can have this repaired. I should have taken a picture of it before I boxed it up, but things are moving fast in my move to Italy. Cheers gentlemen!
