Thank you. That is a start!!

Can anyone tell me what these digits are for on our 66 Chevelle trim tag. We know what everything else is, but these two we are not sure what they are. Any help would be greatly appreciated and and direction on who to ask if no one know. We have asked several people and they say they have never seen it. See the circled 1X on the trim tag. Thank you in advance
