I would not recommend "upgrading" to 12 volts your '55 C300. My '55 C300 cranks and runs great with single 6 volt Optima hidden in a "cloaking device". 15 years ago I focused upon a new wiring harness, new 1 gauge battery cables with clean grounds and connections, refreshed starter and generator and new voltage regulator. This process has worked well over the years with 6 volt Porsche 356's to which most enthusiasts would not want "upgrade" to 12 volts either. Good Luck, Bob. And, Merry Christmas to you!
