Tuff Wheel Adapter does not fit

I don't know how you can ID the column years but I tried to take a steering wheel off of a 70 valiant and installed it into a 75 valiant and it did rub the turn signal cam and also pushed the horn roller all the way down tight. Like I said I don't know if its relevant to this situation but it's just something I experienced in the past.
Ok well that answers it. 70 is a one year only wheel. 71-76 wheel will work on your 75 column.
