The batteries are available. Here is one source and there are others.http://www.antiqueautobattery.com/prod011.htm

You might also check out Fifth Avenue garage. They have information that might be useful if you go ahead with the project.http://www.fifthaveinternetgarage.com/parts/index.html

Your wiring harness will work fine if it is in good condition but there will be several who will give you an argument as to whether the change is necessary. One thing that really dims lights and causes hard starting is poor connections--particularly the grounds. Another is size of battery cables and the modern replacement cables just will not do. 6volts is much fussier in that regard since not much can afford to be lost. The car will work with positive or negative ground as nothing is polarity sensitive in those years other than the radio. Some of those are isolated enough internally to not care. Normally, the car was positive ground and if the coil is still wired that way, there will be a slight loss of efficiency.
