Wheel compatibility

["Peter G. Rossato" <rossato@erols.com>]

I have a set of Audi wheels mounted with Nokia Hakkappellittas.  The wheels have a 4 x 108 mm bolt hole pattern.  They are used on a 5000s Wagon.  Tires are 185/70R14.  The wheels are stamped on the inside 6Jx14H2.  They are also stamped with LFWRONAL, which leads me to believe they are made by Ronal.  They are almost a flush disc, but have 5 slots about 4in x 2 in around the rim edge.  The center has a small disc plug with the Audi 4 ring logo.  

Someone is interested in buying these for a 1990 90 20v Quattro.  I bought the wheels used and think they came from a 90, plus I've seen the same wheel on a 90 recently.  Can anyone confirm the appropriate fitment of these wheels on a 90?  Can you also tell me what other models they would fit?

TIA
