Positive ground alternator?

["Paul" <9laser3@bright.net>]

  I'm looking to replace a positive ground alternator in a 1964 Datsun 1500.
Since Datsun never brought too many of these little cars in to the states,
finding parts is rough.  Does anybody know of another car that was imported
that used a positive ground alternator?  I seem to remember burning up one
in a 1970 Ford Cortina by wiring it backwards to the battery.   Were they
positive ground or is my memory finally gone too!
