NASCAR Racing: Old nascar stats, nascar stats, nascar races

Question
I need to know how many nascar races (mopar) won until the date they pulled out of nascar, back in the day.And the date of the last race they ran before leaving. Thanks a lot.I have a bet going.

Answer
Between Chrysler, Dodge and Plymouth, Mopar claimed 410 wins, the last of them in 1977 when Dodge claimed 7 wins. The last race for Mopar before the return of Dodge in 2001 was the 9/15/85 race at Dover where Maurice Randall started the Randall Racing Chrysler. It was a rather auspicious run when he ran exactly one lap and retired with overheating problems, starting and finishing 39th of 39 starters that day.
So who wins the bet?
