I use an Interstate MT-26 in my '54 3104 converted to 12v. The dimensions are smaller than an original 6v batt for the truck. Only 525 CCA. Not a lot of freezing / cold start weather in Central FL, so that works OK.

Eventhough the terminals are on top of the battery, the cable connectors touch the reproduction battery top retainer. So I used an angle grinder to remove the area of the retainer that touched the connectors.

chadkiser - That's exactly what I did to hold the battery in my '54 before I adapted the retainer. Painted mine black to satisfy my obsessive personality!
