Speedo gear question

Does anyone know what the correct speedometer gear would be for a 1977 production date 4spd manual transmission, part number D7DR-7006-A-A. Its a 2wd tranny for a big block. The gear ratio in the rear end is a 3.92, and im not sure if this make a difference or not but the speedo head is a 1963 unit. Thanks!
