You can check the coil. If the coil is marked for polarity, whichever side is connected to the distributor will be the ground polarity.
That is, if "POS" or "+" goes to the points, it's positive ground. If "NEG" or "-" goes to the points, it's negative ground.

If really 450 miles, likely positive ground per original.

Mike thanks for your quick reply.
The car has been stored in Michigan and never been used after 1966 [ 48 years]
The actual odo miles are 491 .
I can t wait until it passes the customs so I can take pictures and post them.
