Update: I installed the battery from BatteryCentralMall. It started my stock 67 GTO. Garage temp was 65F. Voltages below measured at battery terminals.

Fully charged open circuit voltage - 12.9V
Courtesy lamp & clock load - 12.3V
Cranking voltage for cold start (min) -8.8V
Initial charging voltage -14.7V

Everything looks good.

Thanks for the update I’m gonna need to do something for my 69 bird and never really paid attention to batteries like this before good to know the spring rings wouldnt have worked w the other one. And that this is strong enough .

Just in case anybody gets stuck with an undersized post, they make repair shims. Never used them, just aware of them. HTH.

I received my battery a few days ago and I also was discouraged by the + battery post. Here's how I made the fix. I took a aluminum ski pole inside diameter of 11/16"and cut a 9/16" piece off and de-burred the inside edges. Next I prepped the post by using battery post tool and emery cloth. Next I used soldering paste and coated the aluminum sleeve and battery post. I then placed the sleeve on the post and used my soldering iron to lay a small amount of silver solder on the top. I then used my Bernzomatic torch and heated the top slowly till the solder sucked down inside the sleeve. I immediately poured cool water over to cool it quickly. I then removed the sleeve and it looks perfect. Installed it in my GTO and fired it up.
