How many 4 speed 454 corvette convertibles were assembled in 1974?

There's no readily available, precise figure for the exact number of 1974 Chevrolet Corvette convertibles with a 454 cubic inch engine and a 4-speed manual transmission. Chevrolet didn't publish production numbers broken down to that level of detail. Production figures usually grouped cars by engine type (e.g., 454), transmission type (automatic or manual), and body style (coupe or convertible). Finding a precise count for this specific combination would require extensive research through potentially incomplete archival data from GM.
