Battery in Trunk Wiring That Exceeds NHRA Requirements

I'm getting ready to go through all of this myself on my 66. Where'd you end up purchasing your supplies (cable, terminals, etc)?
I got the cable and copper lugs here: www.wireandsupply.com I guess they would be okay for the 14 gauge and crimp connectors, but I got them from Amazon before I came across Wire and Supply.
One thing about the 14 gauge copper; if it's cheap, read closer, it's probably copper clad aluminum.
I probably got the shrink tubing from Amazon, too. It's been a while.
