Descrptions and part number from the EPC are as follows
13136972 Self locking nut (tie rod) and 24461287 Hexagon screw (hub)
You should be able to order from http://saabpartsdirect.co.uk/
Personal choice off course but I would probably reuse unless I thought they were damaged removing them.
Thanks for that but its the other part in the picture that I need, the lower control arm bolt. I believe its a torx bolt. I did go to the Vauxhall dealer but the parts counter is closed till Monday. The wishbone is the same as the Vectra C so I would have thought the bolt would be the same too
Normally I would re-use it, and I probably will if I cant get new ones, but the Haynes manual does say to replace it.
Ignore what I just said above, I googled the part numbers for pictures and you was correct, thanks
Thats all I can find in the EPC...item 34 "hexagon screw"
Yep its called hexagon screw but its actually a torx bolt, found them on vauxhallsuperstore.something for a quid each and 40p for the nut. The postage is costing me more than the parts
