WTB: 2003 Cobra (or equivalent) Engine Fuse box and power distribution harness

[sonicmach1]

I am looking for a parted out engine fuse box unit and / or the full harness that it attaches to.

Example from an old SVTP post.

I think the nut on the stud on the fuse box in the engine bay is locked on. I am looking for a potential replacement should my work to remove it fails.

Thank you!
