Yeah, any NAPA should have it. It's a bit pricey, I think it was about 6 bucks for a foot of it. It's also a little larger than what you need, but I guarantee the wire won't melt again, lol.
When you ask for it, I believe they told me it was for repairing some kind of exhaust crossover pipe on something, I don't remember now what it was.
