Unusual things on my 1966 barracuda

Yes, that would be early for a 1967 model. This is a late date for a 1966 ? Is the shipping order number of 265 mean that it is the 265th car from that plant that day ?

SO718 is July 18 which would be late, sorry but the 265 doesn't make sense. It's just a order number and not a sequence number.
