Hi 007,
Like you i would like to replace both my CV's the one makes a noise and the other the cotter ring is causing the ABS to trigger due to the corroded teeth.
As for parts from our friends in Swansea they come from the GCP warehouse which hold old Volvo parts.

As for Volvo they will be renovated and cost a fortune. Where possible i try and have the "Volvo" part but if you know who is the OEM manufacture buy them.
I've tried that German website before autodoc but i find the French one MisterAuto are very good.

Just my two pennies.
