Cal 2-27 wheel
I have a 1980 227 with a diesel engine, and your wife is right, steering under power is awful. After my first 5 hour trip I knew I had to do something. What I did was purchase an autohelm self steering unit. When the engine is running at about 80% or less of full speed the unit controls very well. At higher rpm it does long slow s-curves. It is a great thing to have for those long drives.About the wheel, some 227's have a wheel it might even have been a factory option.
