1979 Dodge Cobra remodel....Welcome to help suggestions

I bought US brand 6-volt golf cart batteries equivalent to Trojan 105's for $99 each instead of $150 each for T-105's. I replaced the old converter charger with a Progrssive Dynamics 45 amp unit. Modern converter chargers do not overcharge and boil out batteries .You still need to check electrolyte levels and add distilled water when needed to cover the plates.
