Tundra's rusty parts

Will Toyota replace other parts when they replace my 2002 frame as per the recall? If certain parts are likely to be compromised in the swap, do I pay for those or would Toyota pay?

My mum went through this and it came out great.

There are certain parts they replace but other like exhaust,shocks they do not. They charged Toyota parts prices to her but no labor so it worked to her benefit.

What parts are you concerned about?
