Thanks for the great information. It will not go to waste as I am sure there will be more challenges involving rust in the front end.
Once I managed to press the shafts out I removed the shells. I was surprised the new ones are brass , the old ones were all steel. Except for the one in two pieces the others put up a bit of a fight before removal. I then scraped down the insides of the uprights and wire brushed the internal surfaces then covered them in grease. I checked out the cost of having 321 SS replacements for the liner shaft and it was more to have them done than the entire shaft repair kit. And I would have had to wait 2-3 weeks.
So that plan was shelved and I pressed in the brass bushes - this was not so hard and can be done in a decent sized vice with lined jaws. Just be careful they stay straight otherwise you could wreak them. The inner shaft liner can be drifted in with a timber mallet once both bushes are in.
Just make sure the brass bushes and the inner shaft ends are flush both ends when your finished. It may need a touch in the press to finish them off.
They sure look a heck of a lot better now !
