Negative Battery Cable – Aftermarket – “Off the shelf”?

Does anyone know of a source that sells negative battery cables, with the body ground having a terminal (not a butt connector like the auto parts stores ones have) in ready made lengths? (See photo) I bought this 24-inch one 20+ years ago. Now I could use a 30-inch one. This is for my 72 Imperial. Thanks for any info and/or leads!
