vocky I had a look at it a few months back its the 2010 end case you used to be able to get them off ebay for £110 with no bearings but they dried-up that price is great including the bearings did it say anything about the shimming ? I may get one if I have issues

had some strange vibration after doing the drivers side shaft so went in to investigate
top = vec c z22se f23 5 speed
middle = vec c z22yh m32 6 speed
bottom = astra vxr m32 6speed

the z22se bracket only suits the middle shaft for the m32 it must be the f23 is wider at the shaft entrance

got to mix and match lol
i ended up putting the astra g outter cv on the z22se solid vectra shaft

took the hollow shaft out and fitted a solid one in hope for strength in the future
