Personally I think it would be less labor to just replace that center shaft. Probably not going to be able to find that shaft for sale new. There are a few vendors on this site who may be able to help you with a used one. You could place a want to buy ad looking for what you need but you need to be a paying member to post want to buy ads.

With that being said I have no idea the condition of the rest of your steering column including upper and lower bearings. That information may change my thoughts towards replacing the whole column.
