G ~ Center console [RPO D55]	H ~ Heater delete [RPO C48]

⁽¹⁾ Found on 11B Kansas City tag but tag is suspect for several reasons. Also found on Baltimore trim broadcast sheets so, while the code appears to be valid, its appearance on a trim tag is probably not.
⁽²⁾ Standard 3-speed transmission on all SS396 but so far only Kansas City and Framingham tags have surfaced with this code. Atlanta is known to use no code when no optional transmission is ordered. Neither Baltimore nor Fremont used group option codes.
⁽³⁾ The letter "K" has only been found on Framingham tags and is assumed to be air conditioning since no Framingham tags to date have been discovered with the letter "E" in group 2.
⁽⁴⁾ Unknown, found on an 11D Kansas City Malibu convertible body plate.
⁽⁵⁾ Debate whether this does indicate the optional M21 close ratio 4-speed. It has been found on numerous trim tags with known M21 option and the "L" code is not present. >> Update, November 2011: One July 1967 L78 Chevelle from Kansas City shows "L" on the trim tag and various paperwork with the car clearly indicates an M21 4-speed. It's possible the letter "Q" was dropped late in the 1967 model year but there are no facts to support either theory.

Group 3 - preceded by the number "3"
B ~ Rear window defogger [RPO C50]

Group 4 - preceded by the number "4"
F ~ Operating Convenience Group ⁽¹⁾	H ~ Unknown (found on Baltimore trim sheet)
N ~ Found on fake tag ⁽²⁾

⁽¹⁾ Not verified with RPO code, found on several Atlanta and Kansas City body plates. ⁽²⁾ Found on Kansas City 04A and 06D body plates. Suspect these body plates are reproduction. There was a guy making the fake tags that always put 4N or 4K (L78) on his fake Chevelle tags until someone outed a fake car and the news got back to the trim tag guy that those codes were not used on Chevelles, so he stopped doing that to his fake tags.

Group 5 - preceded by the number "5"
B ~ Front/rear bumper guards [RPO V30] (unverified)	C ~ Reported to be regular shoulder belts [RPO AS1] ⁽³⁾
J ~ Reported to be deluxe center seat, rear [RPO AL5] ⁽¹⁾	M ~ Reported to be regular center seat, rear [RPO A68]⁽²⁾
Y ~ Deluxe seat belts [RPO A39]	Z ~ Shoulder belts [RPO A85]
⁽¹⁾ Found on Framingham 11A and 03F trim tags.
⁽²⁾ Found on Framingham 11D, 01A, and 06C trim tags. Reported on Framingham 05B body plate but cannot confirm.
⁽³⁾ No examples.
