There was a 1969 Baldwin/Motion Camaro under restoration on the Speedvision program called Fantasy Garage. It is a Daytona Yellow 4sp car with a 454. The owner had documentation and stated that Joel R. told him that Motion did build some 454 1969 Camaros. Since the 69 Camaro ran late he used the 454 as it became available if that is what the customer ordered. I have not heard of any convertible Motion 69 Camaros. Since the post drifted to 1962 Belairs, I thought I would add a link to a interesting web pic of Dyno Don and Strickler.
