What are some tips on removing and replacing brake lines etc when replacing the rear end on 97 Dodge 1500

I am asking about the metal block with the main brake line comes in and the rear brake lines and vet lines go out. Can I pry it off and put it on the replacement rear end. I do not have the tools or experience to replace the diff and pinion. I am asking about the metal block with the main brake line comes in and the rear brake lines and vet lines go out.

The block has a bolt threw it. The block is brass and the bolt is steel. The bolt locks up in it, always. Dissimilar metal corrosion. Me, working at a shop, I have to replace the hose and brake lines, insurance stuff. On my vehicle, I replace it all. If money is tight. I cut the bracket that holds it. Again, those lines will have to be moved a bit. Really rusty, they can break and leak. The block has a bolt threw it. The block is brass and the bolt is steel. The bolt locks up in it, always.
