As most know 1962 was the first year the Alum. P/G was assembly line produced chevy. The 1959 Conv. O/SA that Mark Y. mentioned has a reward trans mount (X frame) like the early Corvettes of Marv Ripes, Hoffman, and others that ran in 70-71, etc. In 1972 the alum. P/G was allowed in the 55-57 Chebbies in S/S with an added trans crossmember. My old brain cells are still kind of working.
