I found it! June/July 1991 issue of Mopar Muscle. I guess the car had more equipment on it than I remembered This is the shot as they originally found it. The louvers were still there along with the rear wing! But the trunk and the intermediate panel between the trunklid and the rear window were rusted.
And to think they bought it for around $5,000 back in 1990 and I think they sold the project for about $10,000 in 1992, after it sat in my yard for about a year overtaken by kudzu vines.
