Hey there Jonathan
Welcome to THE place for owners of old Chevrolets!
Forty ones, and especially Special Deluxe coupes are pretty cars and I'm sure Charlie will be here shortly to affirm that.
In the mean time...
Do you need to rewire due to the condition of the wiring? Or to make the accessories and gauges work with 12 volts?
Either way, I'd seriously consider converting back to 6 volts.
I find the 6 volt system to be just as effective and reliable as 12, and everything in the car works with 6 volts without all the conversion issues.
And it brings back the originality too! :-)
PS
Good generators and regulators and good heavy battery cables aren't too hard to find either.
Also, chances are you still have a 6 volt starter, but you would need to confirm that.
