[need RX7]

Still working on my 'resto-mod' project. I plan on 'rebuilding' the battery cables with new terminals, lugs, and quality welding cable.

I want to replicate the stock layout, but I don't know what to do with the positive battery terminal. In stock form, there are two cables that come out of the positive terminal, one to the starter and the other to the fusebox.

Looking at replacement battery terminals, I can't seem to find one that will accommodate two cables. I'd like to avoid just jamming two cables into one of those ones that uses the bolt-down clamp. Any products available that I'm missing, or should I slightly modify the stock setup? I suppose I could run one thick positive cable to a junction near the battery then run the two cables from there.
