Metal Tank Cross compatibility

[NSB001]

Hello, I have a damaged metal tank off a 2021 air cooled monster. From previous owner. Was looking for a used tank. Do I only look for air cooled monster tanks or do water cooled fit as well?
Do I stay looking in my cc range?  Or do bigger displacement model have same tank or bigger?
Tried searching part numbers but the different Color’s have different numbers. It’s a bit confusing.

Air cooled 2021? 797?

It has become increasingly difficult to mix & match over the years, so I'm not sure you'll find a solution.

An introduction, including bike model, of OP would be nice and useful...

The Bike is 2021 659 ABS Monster.

Same tank as the 797 (which is very much the same bike). As far as I can see online - the only alternative for you. These two bikes seem to have a unique frame, so any other tanks fitting is not likely. Theoretically possible, but not likely. As always; anything is possible with the right modifications.
