67Dart273, I did double check but I'm pretty sure that mine only goes in 1 way based on the splines lining up. There is a groove that is wider on the steering box shaft and the coupler and if they are not lined up it won't go together.
true until the coupling has been separated from the shaft. This is where the master spline at steering wheel end comes into play. The coupling box can be put on the shaft 180 wrong.
