Welcome to the Team John!
White on white is unusual for the top (usually the sales manager who orders the car for speculation to buying public orders a blue top with a white exterior, or red if it has a red interior. White is unusual.
I also noticed you have rally wheels. Do you have disc brakes hiding behind them? The stock wheel size back in the sixties was a 14 inch wheel, with the 15 being used with disc brakes and on cop cars or station wagons that also had HD brakes.
