Audi 90 Quattro 1990 California Edition

[Olli]

My 16 yr companion has suffered of unusually many problem, the latest 
total overhall of the rear suspension which did not include the replacement
of the top flanges of the shock absorber assemblies. Shortly after the 
repair shop one of the top flanges gave away. Usually I woulg go to 
Partsbase.org to find
the correct spare code. Not any more I found out. Anybody kind enough to 
assist me - very much appreciated. Rgs, Olli
