Broken cargo/trunk area XP900

So I rolled my XP 900 and broke the interior portion of the cargo area 400.00 for a new one. I would rather fix it. I have all the pieces so it was not just cracked but broken as well. Everything lines up great so I am just curious what everybody recommends as far as plastic welding or rigid plastic repair? There are so many kits and options out there. So if anybody has hands on experience with a good product I sure would appreciate the help. Thanks…
