I am about to replace the bushings in the Steering Coupling on my 73’ 450SE since the ones that are suppose to be there now are gone. The coupling is one of the ones that you can rebuild (had a battle with the local dealer on that one). I wanted to know if you can separate the 2 pieces of the coupling enough to slip in the bushings without having to take out the steering shaft from the steering wheel? There seems to be enough play but I thought I would ask the question before I start. Thanks.
