Which Optima Redtop Size?

The parts store near me has 2 sizes. 75/35 and 78/34. I have a 2000, which size do I need that will fit and not move around? I want to re-use the stock battery hold down since the store doesn't carry the optima one. Thanks.

All fit. The 34/78 is a little larger and higher CCA (and more money). It also has the top posts a little farther apart which matches the 04 battery cable placement a little better.
