NOS 7/16x 5/16-18 negative terminal bolts. You get all 5 in the box. I’m not 100% sure on the application for these. $50.00 plus shipping.

What side mount battery used 5/16-18? I have only seen 3/8-16.

At Chevrolet:
Late 69 L6, 302 (Z28), and 307: The standard battery became the Delco Y77 with side post terminals and the same 45-Ahr rating. The Y77 had two different size terminals, a 3/8-16 positive terminal and a 5/16-18 negative terminal, so the terminals could not be interchanged.
Late 69 350, 396, and 427: The standard battery became the Delco R79 with side post terminals and the same 61-Ahr rating. The R79 battery had two different size terminals, a 3/8-16 positive terminal (positive terminal inboard) and a 5/16-18 negative terminal, so the terminals could not be interchanged
