as Fred said, the 55/6 column is 4" longer than the 57-9 .... the longer column uses a flat steering wheel, the shorter [later] column uses the dished wheel [which is about 4" 'thicker'] .... if you are set on having the "correct" wheel for 57, you'll have to suck it up and buy a correct column, obviously you have the earlier, longer one, which will work fine ohwell
