Vauxhall Owners Clubs
excellent source for finding those rare parts for your classic
Vauxhall is through the various owners clubs located around the world. Many clubs have exclusive new parts sources, having commissioned manufacturers to make obsolete parts that are in demand. You will normally have to join the club in order to take advantage of this supply, but the small registration charge could be a great investment & save you an awful lot of time!!
Also, some owners clubs have discussion forums
and an ads page where members can advertise any parts that may be
surplus to requirements. Interaction with owners club members could
also lead you in the right direction to locate the elusive Vauxhall parts you need.
