Pulled down the steering column; the first thing I noticed was that the end cap came off as soon as I undid the screws as the lash adjustor was not engaged.pitman shaft gear was rubbing against it. I will need to check the end clearance when it goes back together to see if it is worn. If it is I will build it up and then cut it back to spec. It also has a good worm drive and bearing surfaces; again because it was well greased, but using a GP grease as opposed to moly.
I think that the selector shaft is in good condition and the selector connection is sound.

On closer inspection of the one I had already it appears that a washer has been welded onto the shaft to stop the selector from being prised off the shaft. I assume that there was some issue there at one time. I will grind the washer off the back and remove the selecotr shaft tomorrow. The indicator mechanism and horn contact came with it an are also in good used condition.

My plan at this stage is to determine which selector shaft is best, clean up the original one and put it all back together, then repair/reinforce the original selector shaft and put the other one back together as a spare.
I did not get to stripping down the front end today but it does look in pretty good nick. Rob, I'll let you know what I find in relation ot the control arm shafts when I get to that bit.
