My cars build date is today any body know there's?

Mine says 915 which means my 68 fish b-day is Sept.15,1967.

Mike yours is a 66 right. Which means your date would be the first 3 numbers on the third line from the bottom of your fender tag.

If the first character is 8,9,A,B,or C it would have been built the previous year. the last two numbers would be the day of the month.

Like for 1968 model year.
8= Aug. 1967
9= Sept. 1967
A= Oct. 1967
B= Nov. 1967
C= Dec. 1967
1 to 7= Jan. 1968 to July 1968
