Crankcase Side stand engine mont cracked - replace or repair?

Hi,

While my bike was parked, someone drove into it and I wasn't there but they have admitted liability. This is now going thought the insurance.

I was told at first that they were going to replace the broken parts. Now I got the insurance quote and they don't have the crankcase replacement they just said they would repair it.

So should I be ok with a repair or should I insist on a replacement and what argument do I use?

Thanks,
