You can not go by the body, it is unreliable for measurements. All you have to do is lean hard against the quarter and you can change the measurements. If you want to verify that the quarters are the same, take the wheels off and measure from the side of the frame to the lip of the wheel well. Alot of people have posted on here about having to space a rear wheel on one side, I think most G bodys are off from the factory. If the back spacing is off that would account for the difference you are seeing in your measurements, you should never measure off the tire either they change with air pressure and load.
