Years ago, when Sears & Roebuck used to print a foriegn auto parts catalog, I would use their STOCK numbers as a guide to parts that were interchangeable between various european auto manufacturers. It was surprising how many of the same component parts wound up in Italian, German, Sweedish, French & English cars.
An amusing note was that, using the catalog as a guide, I found that a starter for the automatic-stick-shift VW was the same as for my 912 Porsche. The prich for a used 912 starter at the local junk yard was 2-3 times the price of athe VW.
Today, I would think that the junk dealers internet sites probably have the capability to readily cross ref parts.
