Opel Corsa GSi Air intake pipe

[MichMid]

Hi  I have a friend living in Tenerife who has been without her car for over 3 months as it needs an new air intake pipe.  Her car is an old classic (32 years old). I have tried to source the part for her here in the UK through my local garage but they keep sending the wrong part.  Is there anyone on here can help? The Vauxhall people advised the garage to look at the Vauxhall owners club.  Any help would be appreciated.  The vin VSX000093N4018037.  Thanks
