I am looking into upgrading my 40 Graham from 6 to 12 volts and have been doing some planning as to what parts I will need for the conversion. I believe I have most of the problems worked out, but I have two questions.

First, the Graham's electrical system is 6 volt positive ground and I want to switch it over to a 12 volt negative ground. What needs to be done to make this switch?

Second, the headlight system uses a bulb and cannot be easily changed to sealed beam. The bulbs used are marked as GE 2320 which appears to be the model number (they also have printed on them "32 & 320 6 - 8v.") I have no idea whether this is a commonly used bulb for this era or not. Does anyone know if there is a modern 12volt bulb replacement or is there a conversion to halogen bulbs and where would such replacements be available?
i look in to this the bulb is ez to find in 6 v not hard to find but have not found a 12 volts replacement every one went to seald beam i think you may find some thing in 12 volts i think you can just use a conversion kit like for a old ford
