So in 1971 on Cudas and Challengers Chrysler used a machine to roll the numbers onto the motor and transmission. Does anyone have any picturs of such a piece of machinery. I ask this because I was wondering just what the machine looked like to be able to be held against the motor and later the transmission so the rolled press would happen. If there was not a way to hold this machine against the motor and then the transmission then there would be not enough pressure to complete the stamping.

I have seen the stamp or punch that was used via changing the numbers and hitting the punch with a hammer. I can see by going to the 1B###### you would only have to have one punch in 1971. Other years that use complete VINS would have to have many punches or have the ability to change not only the numbers but the letter. Example RS,RM,WS,WM
