Word around the camp fire is that this part will work for our 4WS Preludes. I can't confirm or deny it yet but I'm gonna order two of them and find out.
The part number is in the picture.
It's a Vectra part btw.
Works for me, a few others have used them too with success.
There is one member on here who said they had an issue with the tapered bit not sitting firm in the knuckle, so it would be good if you could let us know how you get on as its thrown a little doubt into the mix.
