A fellow enthusiast paid a visit and was asking questions about it. He thought my hood hinges were from a 1970 based on his reading of the code.
66 and 70 hood hinges don't interchange so I guess your comparing the date codes. Correct?
66 upper - 70 lower

Intellectual curiosity drives me. What am I looking at on said hinges?
