I can't comment on the interior trim. My limited decoding skills suggest that the car was optioned with "exterior molding group?" The only other thing I can infer is that the car had a red, standard interior.
With regard to the Fisher body number "70", I would suspect that the car could have been either day-one or day-two. Hopefully, others will offer opinions but you should review the information on "LOS - Fisher Body body scheduling code" found on the CRG page. "S" would have corresponded to a particular day of the month (late in the month, commensurate with week "D". As I interpret the explanation, the second part of the code "067" suggests that your car was the 67th vehicle that was started down the Fisher body line on that day. CRG explains that the Van Nuys Fisher plant was producing bodies for vehicles other than Camaro and the numbers referred to ALL bodies begun on that particular day so, it would be likely that your car was very early in the day, especially when compared to other Camaros.
I owned a Norwood '68 Camaro that was tagged O8C and the VIN was 000200. There were fewer different styles on the Ohio line and the production numbers were higher as well so I suspect that the '68 was a day-one car as well.
