Generator will need to be changed to an Alternator, and if you get the right one you wont need a regulator. Every thing else will be fine, except the fuel gauge, in mine it is back to front...

The generator can be repolarised to -ve earth if you wish to keep it. An alternator is preferable IMHO anyway.
There is a procedure somewhere..............<goes off to look>.

The generator is fine as it is,the earth is the earth on it whether neg or positve....
its the regulator that is changed.You must actually short out one of the shunts on the regulator a few times and that will convert it to neg earth.I have done this and it worked...which one it is I cant remember alternatively it can be shorted at one of the terminals ,that i cant remember which one,all this is done after you have reversed the wires on the coil and the battery.
There is another way that a few use to try and it worked for them
they simply reversed battery and coil and that was it,they drove it and it was fine,they didnt even short out the regulator it just did it itself...go figure...but I saw them do it.But an auto electrician charges little to do it as it such a simple procedure.Go see one if unsure they can do it on the spot,youll wonder why its so easy when you see em do it.
but what you have all forgotten is the coil must have the wires changed around this is the most important thing,you can always tell what polarity a car is by the coil wires.Very simple when the coil has neg and pos on it,the older has SW and I forgot the other, always forget which is which but i think they refer to where the wire goes to.
Example if the positive wire goes to the dizzy then the car is negative earth,
I cant remember the fuel guage being a problem when converted
as earth is earth whether pos or neg,if i remember rightly the 2 terminals are the same power only interupted by the guage thus the body is the earth and that doesnt matter if neg or posive as long as its oposite to the power in the wires.I remember them being fine and Ive had and converted a lot to negative earth.Try your earth at the fuel tank im sure youll find its something else doing it,ive usually been able to fix those and usually the earth or more likely a wire shorting.
Radios are polarised ,and it matters that the polarity of car and radio is matching unless you isolate the radio from the cars body....but the aerial will short it out if not isolated.
