Disco 1 Metal under boot

So one failure on my car was excessive corrosion withing 30cm of the three rear body mounts. It's the metal strip that runs across the back under the boot. Mines got a winch bumper on the back so didn't notice it. What's the procedure here? Cut it out and what do I need to replace it with? Do I have do buy the right shaped part?

New rear cross member if it's serious, may take a patch it's your call as we have on pictures and Vulcan mind probes don't work on a sunday

As said, new cross member or patch .. or suitably sized box section tube, cut to length and welded in after you remove the old cross member. Many off-road oriented vehicles have this done especially when they use a rear winch too.

These guys have a good rep for replacement parts.
