Is a process of discovery.Doing so sure makes it look nice every time you're behind the wheel. If you need or want that seal, yes, the upper portions have to come off.
Puled the custom steering wheel of , the turn signal enclosure was full of dirt.
Need to replace components for turn signal, including turn signal cancelling cam (simply not there),
and have figured out the adaptor used for the steering wheel does not have the two holes to hold the signal cancelling cam (seems incorrect model) .
Have looked up finding the Frant 4160 adaptor is applicable to 1956 column. The instructions do show the use of the cam plate,
admit I find it .... that they do not show the back side of the adaptor so I can verify the presence of the two holes.
Had though of up grading to a more recent column, but seems a proper upgrade could include the steering box itself since newer designs
actually use a coupler between steering box input shaft , and steering column shaft itself (not just a one piece shaft).
