Was 2 batteries not needed in 89 D250 CTD? From pictures I've seen of 1st gens it looks like only one battery in them. Wondering if theres any way to put another battery under the hood somewhere or if it doesnt need that much CCA. I've been told to just get the biggest battery that can fit in it. I have a walmart everstart maxx in it 1000cca 900cca @32degrees. Whats my options?
