Well good news is sorted the location of the fork.
The bearing inside has flat sides and you can actually reach your hand in the opening and use you fingers to line it up.
Once I did this the fork slid in and located
As you can see it is pretty much in the middle now.
So I went on to make a new clutch pipe, refit it and bleed the slave cylinder.
Having had alot of issues with the clutch fork and getting alot of advice I found the bearing in the housing that has 2 flat sides had moved, luckily you can get your fingers in there, so I managed to get it lined up and the fork in.
But now the fork is in place there is no movement, and I am wondering if the clutch plate has seized.
Also bleeding the slave cylinder, the pedal keeps going to the floor , despite fresh fluid coming out the bleed nipple and all the air being out. Use the standard method of having someone pump the pedal and then tighten the nipple when its down but the pedal still hits the floor and stays there.
I have checked the connections and there is no leaks.
So currently the fork is not moving and the clutch pedal is going to the floor.
With the fork not moving it would not allow the slave to move in and out, presumably that would be affecting the bleeding
