Battery Cables for 68 Valiant

if you don't need absolutely look-like-oem, there are guys/companies on the net, which make custom cables, which are really well made, and not that expensive. When I was looking for battery cables for my Cat backhoe, I stumbled onto them.
IIRC, the oem slant 6 positive cable looks kind of crappy to me. It seems a little short, so it's kind of stretched diagonally from batt to starter. It looks kinda crappy to me because the cable doesn't make smooth curves, and it looks like it's routed poorly. Just my opinion, yours may be different.
