Grumpy Dodge parts department - funny conversation...but still no positive battery cable.

Try Dale's Cuda web site. I've good luck there with cables.

Thanks.
I may have to give them a call. They only list the negative cables.

Why not have them made?We make custom battery cables at work all the time. We make all the way up to 0 Ga.

I will go this route if I have to but by the time I measure the cable gauges, lengths, identify and spec out the connectors, find appropriate heat shielding sheath, I could probably do it myself but my hope is that someone just makes the dang part. :D
