Chuck,
This is the combination that I used on our 1997. The 2/0 going to the starter is the big boy carrying all of the positive current to the starter. The other 3 ends are carrying 1/2 of the total power.
2 pieces 1/0 negative. 1 piece 1/0 positive. 1 piece 2/0 positive. I bet the Belden line also has the heavy lug ends, but I didn't need any of those yet.
I spoke with Rob at NAPA in Evergreen this AM, he is looking into the crimping tool, you might want to stop in and chat. Evergreen ain't that big, I was there in late October, stopped in to visit Rob, you are in a really nice area of CO, in the mountains but within Denvers services.
