Being the proud owner of a 1947 New Yorker Brougham and a 1948 DeSoto Custom Sedan, I know the problems of needing a quality 6 volt Battery. Try your local Mack truck dealer...tell them what you need and I'm quite sure they can help. I've been fortunate to find an 1100 CCA 6-volt that starts either of the above mentioned cars quickly and perfectly. It fits the Factory tray for both cars but JUST fits. The last one I bought was in 2001 and the price was $69.00. Just keep it charged. I own an Optima 12 volt and its grand...never owned a 6 volt. Hope this helps.
