They have an internal Allan (hex) bolt. The one's I have were gold plated with the plastic covers. You can do better than E-Bay if you head to your local stereo shop, Best-Buy or WallyWorld most of the time. All normally have Scosche products in the accessories section of audio. No shipping.

I got mine from a high-end store back in the day. Also got this item that has never been attached or charged. Guess if anyone wants a display for a museum I have you one that did not go up in flames.



Yes, it is the 20 Farad and has the optional remote voltage gauge. LOL
