Hi,
If you go to
http://isr.cudlici.com/ and go to the results section, the rsults of the 1979 Trento Bondone event are in the European Hillclimb section. No race numbers there, but it appears that at least 2002s ran, driven by Dieter Kainbach & Luigi Pellanda. Not sure if the results are complete though, 70 cars listed.
Hope this helps
