NASCAR Racing: True Stock-frame cars, holman moody, nascar cars

Question
When did the stock-frame NASCAR cars disappear, that is, the last factory frames before the complete tube-frame setup?

Answer
I'm really not sure who drove and when the last stock frame was driven. It slowly disappeared over the 1980's and I'm pretty sure there were none left by 1988. I can tell you the first custom tube frame was built in 1960 and Ray Fox won in Atlanta with it. In 1963 Holman Moody built a custom tube frame Galaxy that Curtis Turner took to Bristol. The car was so fast that NASCAR made them take it out of the field due to Chrysler's threat of a boycott. The totally custom tube frames didn't become a mainstay until the 80's as the stock car was phased out and the custom from "ground up" car was phased in.
