Exploded View of Steering Column

I remeber seeing one here also. Looked alot like a bearing that goes in a front hub of a front wheel drive car. I think that was going in a early A.
Another member did about the same thing I did, went to a bicycle shop and got a bearing to fit the original plastic hub and the steering shaft. I did put a collar a spring below mine and put the inner race in from the bottom up.
Again... whatever works. All you really need to do is hold the shaft cnetered in the tube.
