I was at american classic website and they have a VIN checker I have a 64 chevy truck and a title for a 64 chevy truck but when I ran the VIN it said it was a 66 I also notice in a LMC book they say that back up lights were added in 66 and my supposed to be 64 has back up lights. Anybody know anything about this or a better place to check the vin numbers? Kinda wondering if I have a 230 or 250 6 cyl now everything I read says 64 didn't have 250 any help or comments are appreciated.
