I think GC is a George L's dealer and stocks the plugs and raw wire.
It's genious how the blunt cut ends of the wire just feed into the plugs, then you screw in the bolt and you're done. At first, I was confused and thought you needed to strip a couple mm's off of the wire. It's so easy, you don't even need to do that!
I'm really starting to consider yanking my Fender Fat 50's, and installing the Antiquity Texas Hots. So much praise about them!
