Thanks for the tip.  I should have thought of that myself.  The pictures in your comment were a little small to identify the car.  The pdf of the full national results listed Mary's car as a 1999 Camaro but it was corrected to a 1973 in the November Sports Car article summarizing the Nationals results.  However, and this was the point of my original post, the two page picture in the front of the December Sports Car still captioned Al Unser, Jr. as driving a 1965 Camaro.  I would have thought that prior to publishing, someone at SCCA or the Sports Car editorial staff would have said:  "Hey, wait a minute, a 1965 Camaro, --- that's impossible."  The Camaro didn't join the Chevrolet vehicle line up until the 1967 model year and it didn't look anything like Unser's car.  Looking at pictures of his car on line, it is practically a twin of Mary's 1973 Camaro.  I checked Speedway Motors' Team Speedway web site and it says the car is a 1970 Camaro which sounds reasonable and is probably why Al Unser chose 70 for his car number.  I hope you can make this correction in your results archive.

Wanna see more? go to Google Images, type in "Solo Nationals Unser."
