Cabbie,
Back in the late fifties I had a 1953 210, 2 door, and I remember spending the better part of an afternoon getting a new wiper transmission and cable assembly installed and adjusted after a cable broke. At that time, I had no manual, and it was all trial and error. The 1953 manual on tcomp seems to have a fairly comprehensive description of how to do it, along with a couple of pictures.
From the 1953 Chevrolet shop manual I assume that this should also be applicable to the 1954. Good luck!
