L"OH" vs L"Zero"

Another thing I just noticed. Look at the “408” sure grip and the “409” special order. Those “0” are skinny where the L”O”-23 is round. I’m sorry but I’m definitely convinced that its the letter O and not the number 0.
Thanks for sharing this…..that date in the bottom corner must be a mistake or something strange.
Not a mistake. It is the correct date. It's the paperwork from a 1966 D/Dart which had the LO23 vin callout. Not the 1968 LO23. I posted it to show what they did to get the LO23's through the build sequence at the plant.
