If I were to purchase an aftermarket steering wheel, what sort of things would I have to watch out for before I buy? Are all steering columns the same diameter? Are there different screw locations? What's a stock 68 442's steering wheel diameter?

 

69-up columns are all the same diameter and cancel cam configuration. 68-older columns are smaller and have year-to-year differences. Be careful when buying a hub for a 68-older Olds.
