I attached 2 pics from the old Car Craft article on the Mr, Norm's car. Some people say this car had a narrowed axle; that is incorrect. The article even states that the front and rear axles were stock width (although you can't always trust magazine articles 100%).

How scary would this be if the axle was slotted where it was narrowed? Yikes, it is scary enough bieng sloted so heavily even without bieng narrowed.

These pics clearly show that the car had tiny little springs that were under the (standard width) 2X3 framerails and the springs are relocated inwards on the beam axle. Axle is not narrowed. Mr. Norm had this exactly the same setup under atleast 1 other car; a red sedan. Maybe even 2 different sedans.
