I have had Two Cuda's both original paint cars a 1970 and a 1971 both cars missing both #'s.. I was also "freaked out about it to the point I spent $30 for a quick consult with Galan on the subject. He assured me it was possible for the Error to be made on an assembly line of 5 metal cars ( they were stamped before painted)all looking the same rolling done the line, and the Dude that stamps, runs to the bathroom only to return to the wrong place in the line.. "poor Quality control at Chrysler in the 70's Common that could never happen!!!
