Battery terminal connection

Positive Battery terminal was corroded halfway through and I thought it would be a simple splice on a new sidemount connection. Nope, it has a wiring hookup from the fuses.
Is this something I can pick up at the local parts store or do I need to go stealership? Or do I need to replace the entire cable?
Never seen anything like it, but this is the only non-domestic car we've ever owned. Thanks for the help.

Looked everywhere, AZone, Checker, even Napa doesn't carry a terminal that you can just splice in like most other vehicles. The stealership is the only place and they only sell the complete harness. $68 and change and had to order it. That should give me time to look around town at the pick and pull. $70 for a battery terminal is crazy!!
Defeated by automaker's exclusivity on parts :-( but not giving up yet!)
