In my experience once you start cutting to replace frame pieces you end up replacing half the frame. Either get a new frame or part it out.
Frame rust settlement was for 12 years from the date sold, can't hurt you ask but don't be surprised if it is denied.OP - Are you aware of Toyota's warranty frame replacement program if you live in the northern part of the US where road salt is used? If that's where you are and where the truck spent its life, have a dealer look at it. My truck's frame wasn't anywhere near that bad when I bought it in 2016, and Toyota agreed to install a new frame as soon as the dealer laid eyes on it.

Sounds like Toyota's selective warranty frame replacement that I've read about continues, and too bad yours isn't covered OP.Thank you for the input everyone. I spoke with both my local dealer and the Toyota corporate customer service line about this. They both looked up my vin and denied any service because the truck was already sprayed in 2012. It's a little frustrating that this rusting was a known problem and the spray they put on obviously didn't work but I also understand that they can't service a truck forever. Moving on!
