Can anyone check a diameter for me please, outer Sierra c v joint where it goes through the upright, I haven't got one to check the size of the tube through my upright

Mine are the lobro type (bolt on), outer diameter is 100mm. There are a few types though, iirc 108mm.

The old ones fit through the upright, new ones don't!! Ask me how I know
To fit the new one, the upright has to come off. I can measure the diameters tomorrow, I have
one of each fitted.
