I've heard the WalMart at $50 something is the same as the Die Hard Gold. 3 year free replacementfrom WM. That's what I put in my '69. Other than that, I'd go Delco. They make *****in' batteries. They never seem to die. I've also "heard" some less than favorable comments on the Optima's. Seems new production isn't as good as it was. Again, it's what I've "heard."
