Ernie,
Here you go: MSD part number: 32139
Or summit part number:MSD-32139

Like I said, it comes with the Opti side of the wire pre-assembled (apparently it's very easy to mess it up, that's why MSD does it at the factory), and comes with a cool little crimping tool and cutting tool to do the other side. The wires are plenty long enough, with even the shortest of the wires being long enough for the #7, or #8 plugs. Just read the directions on crimping really well before starting.
