The repros I have are both spring clip. They came from, I think, USA Parts Supply in Kearneysville, WV, or come to think of it I might have gotten them from Antique Auto Battery when I got the Delco retro look battery. I’m not a big fan of the negative cable as it’s too long for what’s needed. If you find a better option, let us know. That ground strap, though, looks very much like one I sourced from Antique Auto Battery.
