Options and option codes
I need some help. I'm looking for offical info on options offered by the factory on both Chevy and GMC Suburbans, for the years 1967 - 1972. Does anybody out there have copies of the original ordering info, showing all options each year, with the RPO codes. Very confused on what was and was not truely available on these vehicles. Example: The 1967 GMC Suburban sales brochure indicates buckets were available on GMC's '67 Suburban. The Chevy brochure does not list this option for 1967. Another example: Was front air conditioning available before the dual air units in '69s? And for that matter, did the dual units start in 1969 or '70?
