rear end numbers

Hi i wanted to get some numbers off the rear of a 66 corvette . I had very limited success the only numbers that we could see was 10 with gm below it an l220, does anyone know what these numbers mean if anything. Will be great full. For judging purpose 's do the judges check the rear ends numbers, and how do they do that?

Thank you

not sure where you got those numbers. if the NCRS judge is tall, young, and skinny. like me they will send him under the car to look. its not a fun thing. so if its wrong you can hope for a older fat guy to judge

Transmission and differential "numbers" aren't checked in NCRS Flight Judging - only configuration that can be seen while lying on the ground; lifts aren't used in Flight Judging.
