This is the Fisher Body tag stamped early in the body build process before the car went to Chevrolet for final assembly. The 08A is August 1st week. This is the body build date, either a very early build (August 1961 ) or a very late build (August/62). The body number would probably tell which it is, but is cutoff in the picture.
The vehicle is a 1962 4 door 2 seat wagon (0435 ) Body indicates Kansas City build (KC) and missing body number.
774 Is red/ivory bench seat interior and 936 is Ermine White exterior color.
The ACC line I have no info on. 1962 ACC info was different than all other years and even varied from plant to plant.
