Quick OBJ Mesh Adjustment

I have a small OBJ file that needs two very simple edits. First, delete one element that is no longer required. Then take another part of the mesh and reposition it precisely where I indicate (I will include a screenshot for reference).

The overall topology, scale, and origin must stay intact so the updated model drops straight back into my scene with no extra cleanup. Please return the corrected OBJ—and, if you work in Blender, a .blend is welcome too—keeping the material assignments exactly as they are now.

This is a lightweight task for anyone comfortable with Blender, Maya, 3ds Max, or similar. Let me know your turnaround time; I’d like the fixed file back as soon as possible.
