NASCAR Racing: Production Stock Cars, rockingham nc, chrysler cars

Question
When was the last year for production stock cars, my memory the production based stock car went out with the winged Chrysler cars in 72 or 73. Where was the last race that year

Answer
I'm sorry but I'm really not absolutely sure what year that would be. I can tell you the last race of 72 was the Texas 400 in College Station, TX won by Buddy Baker in the K&K Insurance 71 Dodge, the last race of 73 was the American 500 at Rockingham NC won by David Pearson in the Woods Bros 71 Mercury.
