I have a 1967 coupe barracuda with a low serial number and shipped march 1966.

(should read ) It may have been built for Richard Petty . When I got it, it came with a roll bar and partial cage , few options ,3 in the tree auto including a deleated spare tire on the fender tag, Richard petty blue with racing stripes and a story that claimed it was acquired by a long haul trucker and it left in a carport for 30 years after he walked out on his wife . I will post photos soon. The serial number question may be the answer to who drove it .
