In 1974 i bought a 71 Cortez. I loved it.I bought another this week, and intend to restore it to at least look the same on the outside as the one I had. Gold with a woodgrain stripe. It already has wheels for 12×16.5 tires, so I will stay with that for now. I remember when I think I bought the last 10×17.5 tire in the US. But I always liked the wide track aggressive look of the 10×17.5, so I think the 12×16.5 will fill the wheel wells good.
