I was thinking of changing to 12 volt negative ground.

[1928 Sport Coupe]

I have been thinking of changing from 6 volt positive ground to 12 volt neg ground. Before I try to get the 1930 running I need to change all of the wiring. Which way should I go if I decide on 12 volts?
1 Should I buy or rebuild the starter as 6 volt and use the modern type drive? Would this last with 12 volts? I hear the original drives will not hold up to 12 volts.
2 Should I buy or rebuild the starter with 12 volt fields and the modern type drive? I also see Snyders has a rebuilt starter available that has a stud mount for the power cable, but that would require a solenoid and a push button. Has anyone used this starter?
3 Should I go with the new gear reduction starter? I'm not sure if I like the looks of the new gear reduction starter. Has this one proven to be reliable?
There is not a lot of difference between the price on the above choices depending on if I buy a rebuilt starter or rebuild it myself.
I was also looking at the 12 volt alternator kits. Has anyone used a 1960's 35 amp Ford alternator instead of the Delco alt? It would be hard for me to put a GM Delco part on my Ford. I think I have a NOS Ford, Autolite or Motorcraft 35 amp alternator and wiring connection. Would the Ford alternator fit the premade brackets the Model A suppliers have? Has anyone else used a Ford alternator?
Some time the car has had the points replaced with the Modern V8 points and condenser and the NU-REX distributor plate.
I would like to keep it looking original as much as I can. I think the 12 volt would be less cost overall and be more reliable.

Thanks for any assistance.
