Info on AMC Spirit photos taken at Road America

Calling all AMC historians and racing experts!

I have a question regarding the #86 AMC Spirit race car pictures found on the AMX-files. I have not received a reply from Dennis Kupferschmid.

Was the car at the Trans-Am race Trans-Am Road America, despite it not being listed by official results? If it was, then it should be listed on the RSC site.

Can anyone confirm this to include the car in this historical database.

Thanks,
Chris Z
