Default Front rotor thickness

Does anyone know what the thickness is for a new front rotor? Brakes are stock 12" on a 91.

Some are stamped on the inside with it. For mine, I got them at NAPA. NAPAonline.com lists the min. thickness on their site for the ones I have. If you know what brand they are, maybe they are listed.
