I'm sure you're right, Denny, but the "Old Ride" listing says that the V8 models came with either 13" or 14" wheels. Cut from their table :
Model /Tires
Fairlane Six-Cyl/6.50 x 13
Fairlane V-8/7.00 x 13 / 7.00 x 14
Guess we'd have to travel back with Mr Peabody's Way-Back Machine to when Em's '62 rolled off of the delivery truck to know for sure. Not sure it really matters at this point, given that Em's not wanting to buy another pair of wheels & tires.
Think I'm done with this one.
