1.  WARREN - On the inboard side of the wheel spider there is a V or U notch on one of the spider legs which is on Warren wheels only .

2.  NORRIS THERMADORE - A "N.T." is placed on the spider face 180° opposed to the GM65 stamp.  In addition to this Norris Thermadore is the only source which incorporates a flange on the wind clearance slots of the Passenger and Chevelle wheels.
