Offset is the amount that the mounting pad is located from the centerline of the wheel. Positive offset moves the center toward the outside of the car, similar to a FWD wheel. Negative offset moves the center toward the inside of the car, like the "deep dish" wheels of the '60s and 70's.
The Torque Thrusts are my all-time favorite wheels, and will look great on your '72. Just make sure that you get wheels that are designed to fit a C-3, as the back side of the spokes are made with extra clearance for the large Corvette brake calipers.

INFO CENTER
Wheel Offsets
The offset of a wheel is what locates the tire and wheel assembly in relation to the suspension. More specifically, it is the measured distance between the hub mounting surface and the center line of the rim. Below is an explanation of the various types of offsets which are pictured in the above graphic.
Positive Offset
A positive offset occurs when the hub mounting surface is on the street side (the side you see) of the center line of the rim. Most factory rims will have this type of offset.
Zero Offset
When the hub mounting surface is centered within the rim, it is known as a zero offset.
Negative Offset
If the hub mounting surface is on the brake side of the center line of the rim, it is considered a negative offset or “deep dish”.
Note that extensive negative offset can potentially cause increased steering wheel kick-back and place additional stresses on the vehicle's entire suspension.
