I have used this site's body tag analyzer for '67 and '69 Firebirds. The '67 analyzer has inputs for option codes, but the '69 analyzer doesn't. I recall that '67 codes give a lot of good info., as do the codes for Camaros. Info. pertaining to the '69 Firebird analyzer suggests that many records don't exist and codes such as 3C and K498 had internal assembly plant meanings that can't be decoded. How can someone tell if a '69 Firebird was a Sprint OHC car versus a plain OHC car????? Were some options standard on Sprint cars, such as floor shifters or front disc brakes? Is it likely that a Sprint car came with a column shifter? Does a letter or number in the VIN identify a Sprint car?
