Any reason at all for positive ground?

[Brian Moffet]

I have to replace the wiring harness anyway, so I'm thinking just convert my sprite (doing a restoration on it) to negative ground.

The only reason would be for originality.
Be sure to do the necessary re-wire work to the inside of the tach, switch the coil wires, and re-polarize the generator.
Of the many Sprites I converted to neg ground, only 1 needed the heater blower wires flipped. And that took me 2 years to find out it was sucking air out of the car instead of blowing it in. Only one out of about a dozen and I do not know why.
But check it as it will run backwards.

Does a positive ground promote corrosion in/on the metal body ??
I am thinking about the corrosion that forms on the positive terminal of a lead-acid battery, and usually does not form on the negative terminal.

Any chemists or chemical engineers out there who are familiar with the Nernst equation ?
