Main Battery Terminal Fuse Replacement??
 

Looking to see if anyone is aware of a suitable replacement for the 120A / 120A fuse that is on the positive battery terminal? called Subaru and I was told that the fuse is "part of the main wiring harness", even though it's very clearly installed/uninstalled with 3 nuts.

The part# for the previous generation is 82211ca010, but the fuses are 140A / 80A, and I'm not comfortable with downgrading from a 120A to 80A fuse.
