I did not do a column change, but,
in my 79 w/tilt I tossed the original wheel in favor of
a smaller wheel from a Monte Carlo.
I did this for both of the trucks (I no longer have the 78)
Made a world of difference as far as the comfort level goes.
(hell, if I have working blinkers and tilt---I am very happy)
Also the very first thing I did to the 82 Dodge I acquired, was to install tilt/powersteering/smaller dodge van wheel
